No clue about this, how to resolve and after spending lot of time searching on web, came across the following solution. Keeping this for my future reference and it might help for others for same type of problem,

Solution:

If you delete the DB file, it still stays registered with SqlLocalDB. Sometimes it fixes it by deleting DB. We can do this from the command line.

Open the "Developer Command Propmpt for VisualStudio" under your "Start/Programs menu->All Programs->Visual Studio 2012->Visual Studio Tools"

    Run the following commands:

    sqllocaldb.exe stop v11.0

    sqllocaldb.exe delete v11.0


Now execute "update-database" command from package manager console and it will create database for you without any obstacles.

Magento hosting is currently available from hundreds of thousands of providers. The decision of what Magento hosting company to use can be the difference between the success and the demise of a Magento shopping cart website. While any Magento hosting, eCommerce hosting, or even generic web hosting company may look the same at first glance- placed in very simple terms, nothing could be further from the truth.

Security is a topic that's crucial for any eCommerce web site. If your site stores valuable financial info such as credit card numbers and personal contacts, as most Magento shops do, the severity of this topic is multiplied. No organization can afford to risk the devastating effects of having such data compromised. Many Magento hosting environments consist of private, virtual partitions of a server. This protects against a number of potential exploits that can be opened up by irresponsible webmasters that might otherwise share a server with your Magento shopping cart site.

Microsoft Owin 3.0.1 Provides a set of helper types and abstractions for simplifying the creation of OWIN components.

With IIS supporting Owin it is possible to run other Owin-enabled frameworks such as Nancy on IIS. With Microsoft’s web frameworks depending on Owin and not IIS it is possible to run those in other environments, such as self hosting within a process or on a web server on linux running Mono. SignalR and Web API already uses Owin which means that they can be self hosted and other cool stuff. ASP.NET MVC6 which is part of ASP.NET vNext will be completely based on Owin.

FREE ASP.NET Hosting with ASPHostPortal.com :: How to Fix ASP.NET 4.0 has not been Registered on the Web Server Error

clock May 6, 2015 06:54 by author Dan

When making an ASP.NET website throughout IIS 7 in Visual Studio 2008/2010, you can find the following issue:

“ASP.NET 4.0 has not been registered on the Web server. You need to manually configure your Web server for ASP.NET 4.0 in order for your site to run correctly, Press F1 for more details”

This error usually occurs if you have installed IIS 7.x ‘after’ installing .NET. In order to resolve the error, do the following:

Step 1: Open Control Panel > Programs > Turn Windows Features on or off > Internet Information Services > World Wide Web Services > Application development Feature

Check the box 'ASP.NET' . Also in the Web Management Tools, remember to select IIS 6 Management Compatibility and IIS Metabase as shown below.

Note: Make sure that you are running Visual Studio 2010 as Administrator.

Now run the site from Visual Studio 2010 using Ctrl + F5.

Step 2: If you further get the error “Handler "PageHandlerFactory-Integrated" has a bad module "ManagedPipelineHandler" in its module list” or Managed handler is used; however, ASP.NET is not installed or is not installed completely then do a Visual Studio 2010 repair.

Start > Programs > Accessories > Run. Type this command depending on the version of VS 2010 installed.

Silent Repair for 32-bit

%windir%\Microsoft.NET\Framework\v4.0.30319\SetupCache\Client\setup.exe /repair /x86 /x64 /ia64 /parameterfolder Client /q /norestart


Silent Repair for 64-bit

%windir%\Microsoft.NET\Framework64\v4.0.30319\SetupCache\Client\setup.exe /repair /x86 /x64 /ia64 /parameterfolder Client /q /norestart

That’s it. Restart IIS and the errors should be fixed.

Step 3: If the errors are not yet fixed, there could be an issue in the Application Pool. Follow these steps

1. Open IIS Manager (Run > Inetmgr) . Expand the server node and then click Application Pools

2. Now select the application pool that contains the application that you want to change. Go to Actions > View Applications.

3. Select the Application pool to change > In Action Pane, click on ‘Change Application Pool’

4. In the ‘Select Application Pool’ dialog box, select the application pool associated with .NET 4.0 from the Application pool list and then click OK.
