This post explains about Dynamically assigning Metadata to a page using code behind in ASP.NET 4.0. Metadata is so important as Search engine optimization considers Metadata keywords and description to index  the page. If you can dynamically assign the metadata to your page then search engine can easily analyze and puts the page in results list.

1. Create a ASP.NET web application in VS 2010 and add a grid view to the page

 

2. Configure the SqlDataSource to grid view with Address table as shown below

 

3. Run the application then you will see the following page

 

4. Right click the above and you will notice that there won’t be any meta tags in the page source.

 

This could be problematic for SEO search engine. One solution is you can go to the page and statically can give the meta data description and keywords. This won’t help for the website where data is dynamically updated and want to update their page meta tags according to their generated data.

5. Now We will display the list of sales persons from particular city and update the meta tags accordingly.

6. In code behind for the above page write the following code

string strCity = Page.RouteData.Values["State"] as string;
Page.MetaDescription = "A List of sales persons from " + strCity;
Page.MetaKeywords = "Lists, Sales person" + strCity;

The above code gets the city value from the routing URL and then appends the value dynamically to the page meta description and keywords.

Now run the application and you will see the following output in the page view source.

You can notice that meta tags are update based on the visited cities and this description updated dynamically whenever the city value changed in the URL.

ViewStateMode – ViewState for Individual Controls

ASP.Net 4.0 allows view state in a page to be more controllable from page to its child controls level. That is, view state of a control can be enabled or disabled irrespective of its parent control’s view state. Even if view state of a page is disabled, controls of the page can have their own view state individually enabled or disabled or even inherited from the page’s view state mode property. This property if utilized properly can certainly boost performance of a page.

For example, we can individually enable or disable user control’s view state in a page.



By default, ViewStateMode is enabled for a page object, while controls have inherit mode.

Page.MetaKeywords and Page.MetaDescription – SEO Optimization Feature

ASP.Net 4.0 has come up with these two properties that will help developers add meta tags for keywords and description in the aspx pages in easier fashion. Web Search Engines really need these two meta tags for search indexing of any pages. These two properties can be used in a page in various ways. Inside <head> tag or in the code behind or even at <%@Page%> directive level.

However, setting meta keywords or description in code behind will be more useful when we have to add keywords and descriptions dynamically from source like database.

MetaKeyWords is used to store few useful keywords that will briefly highlight important information of a page by tags. From SEO perspective, meta keywords should contain keywords separated by spaces.

MetaDescription is used to add page description in short that will help Search Engines to quickly describe about the page links in search pages.

Prior to ASP.Net 4.0, we have to add meta tags using HtmlMeta control (public class HtmlMeta : HtmlControl) adding into page header as:

protected void Page_Load(object sender, EventArgs e)
{
//
HtmlMeta metakey = new HtmlMeta();
metakey.Name = “keywords”;
metakey.Content = “ASP.Net 2.0 3.5″;
HtmlMeta metadesc = new HtmlMeta();
metadesc.Name = “description”;
metadesc.Content = “ASP.Net 2.0 3.5 Page Description…”;
//Add to page header
Page.Header.Controls.Add(metakey);
Page.Header.Controls.Add(metadesc);
}

In ASP.Net 4.0, we can add in many ways.

protected void Page_Load(object sender, EventArgs e)
{
//Adding Page meta tags information
this.Page.MetaKeywords = “ASP.Net 4.0 SEO Meta Tag”;
this.Page.MetaDescription = “Serializing and Deserializing Thoughts..”;
}

Or,

<head runat="”server”">
<title>Feature: ViewStateMode</title>
<meta name=”keywords” content =”ASP.Net 4.0 ViewStateMode”/>
<meta name=”description” content=”ViewStateMode feature in ASP.Net 4.0″ />
</head>

Or inside Page directive,



Response.RedirectPermanent – Search Engine Friendly Webpage Redirection

In classic ASP or ASP.Net earlier than 4.0, we used to redirect to new pages or links by setting Response.StatusCode to 301 before calling Response.AddHeader method. Now ASP.Net 4.0 has provided Response.RedirectPermanent method to redirect to new pages or links with StatusCode of 301 implicitly set. Search Engines use this 301 code to understand permanent redirection from old pages links.

For example, Classic ASP method:

<%@ Language="VBScript" %>
<%
Response.Status=”301 Moved Permanently”
Response.AddHeader “Location”,http://www.new-page-url.com/
%>

ASP.Net method prior to 4.0:

<script runat="”server”">
private void Page_Load(object sender, System.EventArgs e)
{
Response.Status = “301 Moved Permanently”;
Response.AddHeader(“Location”,”http://www.new-page-url.com”);
}
</script>

ASP.Net 4.0 method:

Response.RedirectPermanent(“http://www.new-page-url.com “);

Web.Config Refactoring – Custom HttpHandlers and HttpModules

Web.config now looks cleaner as most of the settings are controlled from machine.config file as ASP.Net 4.0 is all set to benefit from IIS 7 and IIS 7.5 features. When IIS is set to use .Net 4.0 and Integrated Pipeline mode, <compilation> element holds .Net version attribute. And the traditional <httpHandlers> and <httpModules> section is now shifted out of <system.web> and added inside new section <system.webserver>. All the custom handlers are added inside <handlers>, and all the modules inside <modules> section.

<system.webServer>
<!– Add the module for Integrated mode applications –>
<modules runAllManagedModulesForAllRequests=”true”>
<add name=”MyModule” type=”WebAppModule.MyCustomModule, WebAppModule” />
</modules>
<!– Add the handler for Integrated mode applications –>
<handlers>
<add name=”MyHandler” path=”svrtime.tm” verb=”GET”
    type=”WebAppModule.MyCustomHandler, WebAppModule” preCondition=”integratedMode” />
</handlers>
</system.webServer>

Also,

<system.web>
<compilation debug=”true” targetFramework=”4.0″ />

Interesting point is, when we add custom handlers and modules this way, we do not have to manually configure handlers and modules in IIS again. IIS will automatically refresh itself.

We know that Gridview and DataList are the Data Controls in ASP.net and they both are used for loading bulk of data however DataList lacks some but the basic functionality such as built-in Paging like GridView Control offers. But that this doesn’t mean than paging is not possible for DataList as you can your custom functionality of paging.

This is quite simple and it can be carried out by adding two Buttons that is the next and previous buttons for navigation.

Below written is the source code that shows how you will do the navigation on DataList Data:

Private Sub BindDataList()
   Dim page As New PagedDataSource

  page.AllowPaging = True
  page.DataSource = ds ‘Here you will write your Dataset
  page.PageSize = 20
  page.CurrentPageIndex = CurrentPage
  dlVideos.DataSource = page     'dlVideos is my Datalist control ID
  dlVideos.DataKeyField = "ID"
  dlVideos.DataBind()

 'according to last and first page...
  imgBtnNext.Visible = Not page.IsLastPage
  imgBtnPrev.Visible = Not page.IsFirstPage
End Sub

Public Property CurrentPage() As Integer

        Get
            ' look for current page in ViewState

            Dim o As Object = Me.ViewState("_CurrentPage")

            If o Is Nothing Then

                Return 0
            Else
                ' default to showing the first page

                Return CInt(o)

            End If
        End Get

        Set(ByVal value As Integer)

            Me.ViewState("_CurrentPage") = value
        End Set
    End Property

'Previous Button
Protected Sub imgBtnPrev_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles imgBtnPrev.Click
        CurrentPage -= 1
        BindDataList()
End Sub

'Next Button
Protected Sub imgBtnNext_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles imgBtnNext.Click
        CurrentPage += 1
        BindDataList()
End Sub

Disabling The Outer Table In Templated Controls

In ASP.NET 3.5, a number of Web controls that use (or can use) templates automatically wrap the rendered templated content within a <table> element. One such control that displays this behavior is the FormView control. To see how the FormView wraps the output in a <table>, let's take a moment to construct a FormView to display the name and description of a particular category from the Northwind database's Categories table. This FormView would need to include an ItemTemplate that emitted the CategoryName and Description fields. The following declarative markup creates such a FormView:

<asp:FormView runat="server" ...>
   <ItemTemplate>
      <b><%# Eval("CategoryName") %></b><br />
      <%# Eval("Description") %>'
   </ItemTemplate>
</asp:FormView>

Furthermore, imagine that this FormView was bound to a data source control that returned information about the Beverages category. When viewed through a browser, the FormView control would generate the following HTML:

<table cellspacing="0" id="ContentPlaceHolder1" style="border-collapse:collapse;">
   <tr>
      <td colspan="2">
         <b>Beverages</b><br />
         Soft drinks, coffees, teas, beers, and ales'
      </td>
   </tr>
</table>

The highlighted markup above shows the <table> element automatically added to the markup defined in the template. In short, the FormView control wraps its templated content within a one row, one column table, whether we like it or not.

The FormView renders this outer <table> to express style information. The FormView has a property named RowStyle, which contains a variety of substyles (BackColor, Font, BorderColor, and so on). For example, if the RowStyle's BackColor and Font-Size properties are set to Red and Larger, respectively, the FormView will render the following markup:

<table cellspacing="0" id="ContentPlaceHolder1" style="border-collapse:collapse;">
   <tr style="background-color:red;font-size:Large;">
      <td colspan="2">
         <b>Beverages</b><br />
         Soft drinks, coffees, teas, beers, and ales'
      </td>
   </tr>
</table>

Note how the <table> (specifically the <tr> element) specifies the style as defined by the FormView's RowStyle property. Therefore, this outer <table> element is useful when using the RowStyle property, but is extra cruft if the RowStyle property is not being used or if the style information is specified directly in the template's markup (using CSS classes, ideally).

ASP.NET 4.0 adds a new Boolean property to the FormView and a host of other Web controls named RenderOuterTable. This property, when set to True (the default), renders the outer <table> element as was done in ASP.NET 3.5 and earlier versions. If this property is set to False, however, then the outer <table> is omitted.

Taking our earlier FormView example, let's see what would happen if we set RenderOuterTable to False.

<asp:FormView runat="server" ... RenderOuterTable="false">
   <ItemTemplate>
      <b><%# Eval("CategoryName") %></b><br />
      <%# Eval("Description") %>'
   </ItemTemplate>
</asp:FormView>

With that minor change, the rendered markup for the FormView no longer includes the outer table. Instead, the FormView renders just the contents of its template(s), as the following snippet of HTML shows:

<b>Beverages</b><br />
Soft drinks, coffees, teas, beers, and ales'

When RenderOuterTable is set to False, any styles that are expressed through that outer table are no longer rendered. In short, any style settings to the RowStyle property will be ignored when the above FormView is rendered.

In addition to the FormView, the RenderOuterTable property has been added to the following Web controls in ASP.NET 4.0:

- Login
- PasswordRecovery
- ChangePassword
- Wizard
- CreateUserWizard

The download available at the end of this article includes a demo that illustrates the effects of the RenderOuterTable property on both the FormView and Login controls.

ListView Control Enhancements

The ListView control displays a set of data records using templates. Like the GridView, the ListView supports paging, sorting, editing, and deleting data. It can also be used to insert data. Developers using the ListView control in ASP.NET version 3.5 had to provide at least two required templates:

- ItemTemplate - specifies the markup rendered for each item bound to the ListView
- LayoutTemplate - specifies the ListView's encasing markup and contains a Web control that indicates where the ItemTemplate's markup should be placed

In most scenarios, the LayoutTemplate would contain nothing but a Web control to specify where the ItemTemplate's markup should appear, resulting in a ListView with markup like the following:

<asp:ListView runat="server" ...>
   <LayoutTemplate>
      <asp:PlaceHolder runat="server" ID="itemPlaceHolder" />
   </LayoutTemplate>
   <ItemTemplate>
      ...
   </ItemTemplate>
</asp:ListView>

The LayoutTemplate in the above example serves no purpose other than to say, "Here is where the ItemTemplate markup should go." Regardless, with ASP.NET 3.5 you still had to define this LayoutTemplate explicitly in the ListView's markup.

The good news is that with ASP.NET version 4.0 you can omit the LayoutTemplate - the ItemTemplate is now the only required template in the ListView. The following snippet of declarative markup shows this new abbreviated syntax:

<asp:ListView runat="server" ...>
   <ItemTemplate>
      ...
   </ItemTemplate>
</asp:ListView>

New RepeatLayout Options for the CheckBoxList and RadioButtonList Controls

The CheckBoxList and RadioButtonList controls display a set of check boxes or radio buttons based on some data and are useful for building a set of check boxes or radio buttons based on a database query. Both of these controls have a RepeatLayout property that dictates how the series of check boxes or radio buttons are laid out. In ASP.NET 3.5 there were two possible settings for this property:

- Table (the default) - lays out the items using a <table> element. By default, each check box or radio button is laid out in its own table row. Use the RepeatColumns property to have a fixed number of check boxes or radio buttons displayed per row.
- Flow - lays out each check box or radio button in a <span> element with a line break (<br />) after each element, by default. The RepeatColumns property, if set, indicates that a line break should only be rendered after a certain number of check boxes or radio buttons.

ASP.NET 4.0 adds two additional settings to the RepeatLayout property:

- OrderedList - lays out the items using an <ol> element. You cannot use the RepeatColumns property with this setting. Doing so will result in an exception being thrown when the page is visited.
- UnorderedList - lays out the items using an <ul> element. You cannot use the RepeatColumns property with this setting. Doing so will result in an exception being thrown when the page is visited.

Consider the following CheckBoxList, which has its RepeatLayout property set to UnorderedList.

<asp:CheckBoxList ... runat="server" DataTextField="CategoryName"
       DataValueField="CategoryID" RepeatLayout="UnorderedList">
</asp:CheckBoxList>

When bound to the categories in the Northwind database the above control will render the following markup:

<ul id="...">
   <li><input id="..." type="checkbox" name="..." value="1" /><label for="...">Beverages</label></li>
   <li><input id="..." type="checkbox" name="..." value="1" /><label for="...">Condiments</label></li>
   <li><input id="..." type="checkbox" name="..." value="1" /><label for="...">Confections</label></li>
   ...
</ul>

Note how the CheckBoxList renders an unordered list (<ul>) and how each check box is rendered within a list item (<li>).

The idea with the OrderedList and UnorderedList options is that the check boxes or radio buttons can be laid out using CSS. There are many web pages that discuss how to use CSS to layout elements in ordered and unordered lists.

Conclusion

ASP.NET 4.0 gives Web Form developers greater control over the rendered markup. Many templated controls that had previously added <table> elements for styling purposes. These tags can now be optionally suppressed with a new property, RenderOuterTable. Similarly, the CheckBoxList and RadioButtonList controls' RepeatLayout property has been expanded to include two new settings - OrderedList and UnorderedList - which offer developers alternative ways to influence the markup generated by these controls.

Also, the ListView control has been tidied up a bit, making the LayoutTemplate optional.

Happy Programming!

So, how do you use these methods?

These extensions add a few simple methods:

MapRoute

Stolen shamelessly from MVC. These methods provide a shortcut to defining Routes for WebForms.

RouteCollection.MapRoute(string name, string url, string physicalFile);

For example to map a simple route you can now do:

RouteTable.Routes.MapRoute(“ProductDetailsRoute”, “products/{productid}”, “~/ProductDetails.aspx”);

Also has a couple of variants allowing for defining defaults etc…

RouteCollection.MapRoute(string name, string url, string physicalFile, object defaults);

RouteCollection.MapRoute(string name, string url, string physicalFile, object defaults, string[] namespaces);

GetRouteForUrl

Page.GetUrlForRoute(string routeName, RouteValueDictionary parameters);

Using a specifically named route and RouteValueDictionary containing a number of parameters will give you back a string containing the Url to use. REALLY useful in databound apps!

For example:

<asp:hyperlink ID="HyperLink1" runat="server"  NavigateUrl='<%# Page.GetUrlForRoute("ProductDetailsRoute",new RouteValueDictionary( new {productid= Eval("ProductID")}))%>'  Text="Details"></asp:hyperlink>

Page.GetUrlForRoute(RouteValueDictionary parameters);

Same thing, but auto-matches the RouteValueDictionary parameters against a route…

IgnoreRoute

Allows you to define urls which should not be tried for matches against routes (can be useful for upgrading WebForms apps)

RouteCollection.IgnoreRoute(string url);

RouteCollection.IgnoreRoute(string url, object constraints);

New Controls

Three new controls have been added to WPF to make it easier to create business applications. These controls are almost 100 percent compatible with the Silverlight versions. This enables developers to reuse code and quickly create client and Web versions.

- DataGrid
- Calendar
- DatePicker

Visual State Manager

WPF provides better support for changing visual states in a ControlTemplate. The VisualStateManager class and supporting classes have been added so that tools such as Microsoft Expression Blend can be used to define a control's appearance according to its visual state. For example, you can define the appearance of a Button control when it is in the Pressed state. For more information about creating a ControlTemplate that uses the VisualStateManager for an existing control.

Touch and Manipulation

Elements in WPF now accept touch input. The UIElement, and UIElement3D, and ContentElement classes expose events that occur when a user touches an element on a touch-enabled screen. In addition to the touch events, the UIElement supports manipulation. A manipulation is interpreted to scale, rotate, or translate the UIElement. For example, a photo viewing application might allow users to move, zoom, resize, and rotate a photo by touching the computer screen over the photo.

Graphics and Animation

Several changes have been made related to graphics and animations.

1. Layout Rounding

When an object edge falls in the middle of a pixel device, the DPI-independent graphics system can create rendering artifacts, such as blurry or semi-transparent edges. Previous versions of WPF included pixel snapping to help handle this case. Silverlight 2 introduced layout rounding, which is another way to move elements so that edges fall on whole pixel boundaries. WPF now supports layout rounding with the UseLayoutRounding attached property on FrameworkElement.

2. Cached Composition

By using the new BitmapCache and BitmapCacheBrush classes, you can cache a complex part of the visual tree as a bitmap and greatly improve rendering time. The bitmap remains responsive to user input, such as mouse clicks, and you can paint it onto other elements just like any brush.

3. Pixel Shader 3 Support

WPF 4 builds on top of the ShaderEffect support introduced in WPF 3.5 SP1 by allowing applications to now write effects by using Pixel Shader (PS) version 3.0. The PS 3.0 shader model is more sophisticated than PS 2.0, which allows for even more effects on supported hardware.

4. Easing Functions

You can enhance animations with easing functions, which give you additional control over the behavior of animations. For example, you can apply an ElasticEase to an animation to give the animation a springy behavior. For more information, see the easing types in the System.Windows.Media.Animation namespace.

Text

Several changes have been made related to text.

1. New Text Rendering Stack

The WPF text rendering stack has been completely replaced. This change brings improvements to text rendering configurability, clarity, and support for international languages. The new text stack now supports explicitly selecting aliased, grayscale, or ClearType rendering modes. The text stack now supports display-optimized character layout, to produce text with sharpness comparable to Win32/GDI text. The new text stack allows optimizing text hinting and snapping for either animated or static text. The new text stack also supports fonts with embedded bitmaps to be substituted for smaller font sizes, allowing many East Asian fonts to render with sharpness comparable to Win32/GDI text.

2. Selection and Caret Customization

You can now specify the brush that paints the selection and caret for input and reading controls, such as TextBoxRichTextBox, and FlowDocumentReader. There are two new properties on TextBoxBase:

- SelectionBrush allows you to create a brush for highlighting selected text.
- CaretBrush allows you to change the brush that paints the cursor.

Binding

Various changes and enhancements have been made related to binding.

1. Bind to commands on InputBinding.

You can bind the Command property of an InputBinding class to an instance that is defined in code. The following properties are dependency properties, so that they can be targets of bindings:

- InputBinding.Command
- InputBinding.CommandParameter
- InputBinding.CommandTarget
- KeyBinding.Key
- KeyBinding.Modifiers
- MouseBinding.MouseAction

The InputBinding, MouseBinding, and KeyBinding classes receive data context from the owning FrameworkElement.

2. Bind to Dynamic Objects

WPF supports data binding to objects that implement IDynamicMetaObjectProvider. For example, if you create a dynamic object that inherits from DynamicObject in code, you can use markup extension to bind to the object in XAML.

3. Bindable Text Run

Run.Text is now a dependency property. The main advantage is that it now supports one-way bindings. It also supports other features of dependency properties, such as styling and templating.

XAML Browser Applications

Two features have been added to XAML browser applications (XBAPs).

1. HTML-XBAP Script Interop

You can now communicate with the Web page containing the XBAP when the application is hosted in a HTML frame. The XBAP can get deep access to the HTML DOM and can handle DOM events.

2. Full-Trust XBAP Deployment

If your XBAP requires full trust, the user will now automatically receive the standard ClickOnce elevation prompt when they install the application from the intranet or one of their browser's trusted sites.

WPF and Windows

The Windows 7 taskbar provides enhanced functionality that enables you to use the taskbar button to communicate status to a user and expose common tasks. New types in the System.Windows.Shell namespace provide managed wrappers for functionality in the Windows 7 taskbar and manages the data passed to the Windows shell. For example, the JumpList type allows you to work with Jump Lists and the TaskbarItemInfo type allows you to work with taskbar thumbnails.

WPF dialog boxes on Windows 7 and Windows Vista now support the look and feel of the Windows 7 and Windows Vista style, which includes custom places.

WPF and Silverlight Designer

In Visual Studio 2010, various designer improvements have been made to help create WPF or Silverlight applications.

1. Improved Support for Silverlight

In Visual Studio 2008, you could install the Silverlight Tools to create Silverlight applications in Visual Studio. However, the designer support for Silverlight projects was limited. In Visual Studio 2010, the designer support for Silverlight and WPF projects are now the same. For example, in Silverlight projects you can now select and position items with the mouse on the design surface.

2. Support for Multiple Platform Versions

In Visual Studio 2008, control design times were able to target only the latest WPF platform version. In Visual Studio 2010, this support is extended across multiple platforms, including design-time support for WPF 3.5, WPF 4, Silverlight 3, Silverlight 4, and future platform releases. As the same extensibility API exists for all these platforms, control design-time authors can easily write one experience and share it across the control runtimes for each platform.

3. Visual Databinding

The new data binding builder enables visual construction and editing of bindings without typing XAML.

4. Auto Layout

Layout improvements include a more intuitive Grid designer and better support for automatically sizing user controls.

5. Improved Property Editing

The Properties window now enables visually creating and editing Brush resources.

New in Visual Studio 2010

Enhanced Docking Behavior
Document windows are no longer constrained to the editing frame of the integrated development environment (IDE). You can now dock document windows to the edges of the IDE, or move them anywhere on the desktop (this includes a second monitor). If two related document windows are open and visible, for example, a designer view and an editor view of the same Windows Form, changes that were made in one window will immediately take effect in the other window.

Tool windows can now move freely between docking at the edges of the IDE, floating outside the IDE, or filling part or all of the document frame. They remain in a dockable state at all times.

Zoom
In any code editing window or text editing window, you can quickly zoom in or out by pressing and holding the CTRL key and moving the scroll wheel on the mouse. You can also zoom textual tool windows, for example, the Output window. The zoom feature does not work on design surfaces or on tool windows that contain icons, for example, the Toolbox or Solution Explorer.

Box Selection
In previous releases of Visual Studio, you could select a rectangular region of text by holding down the Alt key while selecting a region with the mouse. You could then copy or delete the selected text. VS 2010 adds the following new capabilities to the box selection feature:

- Text insertion: Type into a box selection to insert the new text on every selected line.
- Paste: Paste the contents of one box selection into another.
- Zero-length boxes: Make a vertical selection zero characters wide to create a multi-line insertion point for new or copied text.

You can use these capabilities to rapidly operate on groups of statements, such as changing access modifiers, setting fields, or adding comments.

Call Hierarcy
Call Hierarchy, which is available in Visual C# and Visual C++, displays the following parts of your code so that you can navigate through it more effectively:

- Calls to and from a selected method, property, or constructor.
- Implementations of an interface member.
- Overrides of a virtual or abstract member.

This can help you better understand how code flows, evaluate the effects of changes, and explore possible execution paths by examining complex chains of method calls and other entry points in several levels of code.

Call Hierarchy is available at design time, unlike the call stack that is displayed by the debugger.

The member name appears in a pane of the Call Hierarchy window. If you expand the member node, Calls To member name and Calls From member name subnodes appear. If you expand the Calls To node, all members that call the selected member are displayed. If you expand the Calls From node, all members that are called by the selected member are displayed. You can also expand the subnode members into Calls To and Calls From nodes. This lets you navigate into the stack of callers.

Navigate to
You can use the Navigate To feature to search for a symbol or file in the source code.

Navigate To lets you find a specific location in the solution or explore elements in the solution. It helps you pick a good set of matching results from a query.

You can search for keywords that are contained in a symbol by using Camel casing and underscore characters to divide the symbol into keywords.

Highlighting References
When you click a symbol in the source code, all instances of that symbol are highlighted in the document.

The highlighted symbols may include declarations and references, and many other symbols that Find All References would return. These include the names of classes, objects, variables, methods, and properties.

In Visual Basic code, keywords for many control structures are also highlighted.

To move to the next or the previous highlighted symbol, press CTRL+SHIFT+DOWN ARROW or CTRL+SHIFT+UP ARROW.

Generate from Usage
The Generate From Usage feature lets you use classes and members before you define them. You can generate a stub for any undefined class, constructor, method, property, field, or enum that you want to use but have not yet defined. You can generate new types and members without leaving your current location in code, This minimizes interruption to your workflow.

Generate From Usage supports programming styles such as test-first development.

IntelliSense Suggestion Mode
IntelliSense now provides two alternatives for IntelliSense statement completion, completion mode and suggestion mode. Use suggestion mode for situations where classes and members are used before they are defined.

In suggestion mode, when you type in the editor and then commit the entry, the text you typed is inserted into the code. When you commit an entry in completion mode, the editor shows the entry that is highlighted on the members list.

When an IntelliSense window is open, you can press CTRL+ALT+SPACEBAR to toggle between completion mode and suggestion mode.

This topic contains brief information about What’s New in WCF Data Services. If you looking for ASP.NET 4 hosting, you can always consider ASPHostPortal. At ASPHostPortal you can get a professional ASP.NET 4 installation with your ASP.NET 4 Hosting account. You can always start from our Portal ONE hosting plan (from @$5.00/month) to get this application installed on your website. So, why wait longer?

The following new Open Data Protocol (OData) version 2.0 functionality is supported in this release of WCF Data Services:

Counting entities in an entity set

A new $count path segment enables you to receive only the total number of resources returned by a URI. A new $inlinecount query option enables you to receive the same total resource count together with the resource data in a single response.

The .NET Framework client library has been updated to enable you to access this row count information in a query response in your application.

Query Projections

Query results can now be modified to include only a subset of properties by using the new $select query option.

The .NET Framework client library has been updated to support projection by using the select clause (Select in Visual Basic) in a LINQ query.

Partial Entity Sets

A data service can now return a partial list of the entities requested by a URI, together with a URI that is used to obtain the next set of entities in the result. The new $skiptoken query option is used to request the next page of results.

The following functionality is new in this release of WCF Data Services:

Server-driven paging

A data service can now be configured to return requested resources as a set of paged responses.

The .NET Framework client library has been updated to enable you to handle paged responses.

Data binding

A new DataServiceCollection class provides simplified binding of data service data to Windows Presentation Framework (WPF) controls. This class inherits from the ObservableCollection class to automatically update bound data when there are changes to data in bound controls.

Streaming of binary resources

An entity can be defined as media link entry, with a link to an associated media resource. This enables you to retrieve and save binary large object data independent of the entity to which it belongs. You can create a data service that returns binary property data as a stream instead of first loading the entire entity, including binary data, into memory. Do this by implementing the IDataServiceStreamProvider interface.

The .NET Framework client library has been updated to allow you to get and set binary properties as a data stream.

Custom data service providers

By implementing a set of new data service provider interfaces, you can use various types of data with a data service, even when the data model changes during execution.

This topic contains brief information about Windows Workflow Foundation. If you looking for ASP.NET 4 hosting, you can always consider ASPHostPortal. At ASPHostPortal you can get a professional ASP.NET 4 installation with your ASP.NET 4 Hosting account. You can always start from our Portal ONE hosting plan (from @$5.00/month) to get this application installed on your website. So, why wait longer?

Windows Workflow Foundation (WF) in .NET Framework version 4 changes several development paradigms from previous versions. Workflows are now easier to create, execute, and maintain, and implement a host of new functionality.

Workflow Activity Model

The activity is now the base unit of creating a workflow, rather than using the SequentialWorkflowActivity or StatemachineWorkflowActivity classes. The Activity class provides the base abstraction of workflow behavior. Activity authors can then implement either CodeActivity for basic custom activity functionality, or NativeActivity for custom activity functionality that uses the breadth of the runtime. Activity is a class used by activity authors to express new behaviors declaratively in terms of other NativeActivity, CodeActivity, AsyncCodeActivity, or DynamicActivity objects, whether they are custom-developed or included in the .NET Framework 4 Built-In Activity Library.

Rich Composite Activity Options

Flowchart is a powerful new control flow activity that allows authors to model arbitrary loops and conditional branching. Flowchart provides an event-driven programming model that was previously only able to be implemented with StateMachineWorkflowActivity. Procedural workflows benefit from new flow-control activities that model traditional flow-control structures, such as TryCatch and Switch.

Expanded Built-In Activity Library

New features of the activity library include:

- New flow control activities, such as, DoWhile, Pick, TryCatch, ForEach, Switch, and ParallelForEach.

- Activities for manipulating member data, such as Assign and collection activities such as AddToCollection.

- Activities for controlling transactions, such as TransactionScope and Compensate.

- New messaging activities such as SendContent and ReceiveReply.

Explicit Activity Data Model

.NET Framework 4 includes new options for storing or moving data. Data can be stored in an activity using Variable. When moving data in and out of an activity, specialized argument types are used to determine which direction data is moving. These types are InArgument, InOutArgument, and OutArgument.

Enhanced Hosting, Persistence, and Tracking Options

.NET Framework 4 contains persistence enhancements such as the following:

- There are more options for running workflows, including WorkflowServiceHost, WorkflowApplication, and WorkflowInvoker.

- Workflow state data can be explicitly persisted using the Persist activity.

- A host can persist an ActivityInstance without unloading it.

- A workflow can specify no-persist zones while working with data that cannot be persisted, so that persistence is postponed until the no-persist zone exits.

- Transactions can be flowed into a workflow using TransactionScope.

- Tracking is more easily accomplished using TrackingParticipant.

- Tracking to the system event log is provided using EtwTrackingParticipant.

- Resuming a pending workflow is now managed using a Bookmark object.

If you're an avid .NET programmer, you are likely aware of what the above title says. Since the birth of multi-core computing, there has been a need for parallel-programming architecture. Now, the multi-core computing has become the prevailing paradigm in computer architecture due to the invention of multi core-processors. By the way, almost every programmer considers Visual Studio 2008 and .NET Framework 3.5 as getting remote and out of the way. To avert its programming market fiasco, recently, Microsoft released the beta versions of .NET Framework 4 and Visual Studio 2010. The main focus fell on .NET 4, yet the labels boasted the advent of parallel-programming. The question is whether there are any advantages (more specifically towards performance) on sticking to existing APIs? This article attempts to briefly answer the question.

.NET 4's Multi-Core processing ability: First of all, the MSDN site shows that the parallel extensions in the .NET 4 , has been improved to support parallel programming, targeting multi-core computing or distributed computing. The support for the Framework has been categorized into four areas like library, LINQ, data structures and diagonastic tools. .NET 4's peers and predecessors lacked the multi-core operable ability. The main criteria like communication and synchronization of sub-tasks were considered as the biggest obstacles in getting a good parallel program performance. But .NET 4's promising parallel library technology enables developers to define simultaneous, asynchronous tasks without having to work with threads, locks, or the thread pool.

Full support for multiple programming languages and compilers: Apart from VB & C# languages, .NET 4 establishes full support for programming languages like Ironpython, Ironruby, F# and other similar .NET compilers. Unlike 3.5, it encompasses both functional-programming and imperative object-oriented programming.

Dynamic language runtime: Addition of the dynamic language runtime (DLR) is a boon to .NET beginners. Using this new DLR runtime environment, developers can add a set of services for dynamic languages to the CLR. In addition to that, the DLR makes it simpler to develop dynamic languages and to add dynamic features to statically typed languages. A new System Dynamic name space has been added to the .NET Framework on supporting the DLR and several new classes supporting the .NET Framework infrastructure are added to the System Runtime Compiler Services.

Anyway, the new DLR provides the following advantages to developers: Developers can use rapid feedback loop which lets them enter various statements and execute them to see the results almost immediately. Support for both top-down and more traditional bottom-up development. For instance, when a developer uses a top-down approach, he can call-out functions that are not yet implemented and then add them when needed. Easier refactoring and code modifications (Developers do not have to change static type declarations throughout the code)

Parallel-diagnostics: Unlike Visual Studio 2008, the new Visual Studio 2010 supports debugging and profiling, extensively. The new profiling tools provides various data views which displays graphical, tabular and numerical information about how a parallel or multiple-threaded application interacts with itself and with other programs. The results enable developers to quickly identify areas of concern, and helps in navigating from points on the displays to call stacks & source codes. If you think only parallel programming abilities and promising capabilities make the MS .NET 4.0 a more promising next generation programming tool, think again! That's not all. There are also a number of enhancements to the Base Libraries for things like collections, reflection, data structures, handling, threading and lots of new features for the web.
