Using Visual Studio 2013 Express Preview for Web and Entity Framework 5

I'm getting the following error when I attempt to enable migrations:

PM> Enable-Migrations System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.VisualStudio.Shell, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

Any suggestions?

Have you tried RC that shipped last week? You can get the RC from here: microsoft.com/visualstudio/eng/2013-downloads - Pawel
I created a work item to verify this - entityframework.codeplex.com/workitem/1658 but it is most likely fixed in RC. See entityframework.codeplex.com/workitem/467 for more details. - Pawel

I had the same exact issue and finally solved it by installing "Microsoft Visual Studio 2012 Shell Redistributable Package (isolated)" (http://www.microsoft.com/en-us/download/details.aspx?id=30670).

I tried the Redistributable Package mentioned earlier and it did not fix the error. Simply updating the Entity Framework through the NuGet Package Manager did the trick for me.

The issue is also explained here: https://connect.microsoft.com/VisualStudio/feedback/details/805933/filenotfoundexception-enabling-ef-migration

It says it is fixed with vs2013 update 2. But I just tested it with windows 8.1 and update 2 but could still reproduce this.
