Answer 3

Get the latest version of MVC3 via NuGet. Open your project in Dev Studio. Open the Package Manager Console tab at the bottom of Dev Studio. Then use this command:

PM> Install-Package Microsoft.AspNet.Mvc -Version 3.0.50813.1

If you click the tab key after "-Version" you will get a list of all of the available versions.

If you have an old version of NuGet you may get an error indicating you have to upgrade it. If so, open Tools->Extension Manager to install the latest version of NuGet. Note, you will need to run Dev Studio as Administrator before you can install NuGet.

Installing MVC3 should update Web.config in your project.

  </dependentAssembly>
</assemblyBinding>
