REPRODUCE
Install Visual Studio 2013 Preview + ASP.NET and WebTools 2013 Preview Refresh Update
New WebProject, MVC
Update all nuget packages
Run the app, try registering via clicking the link on the top
RESULT
Could not load type 'System.Data.Entity.DbSetExtensions' from assembly 'EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
POTENTIAL ROOT CAUSE
In the change from EF6 beta1 to EF6 RC1 DbSetExtensions has been removed which breaks Microsoft.AspNet.Identity.EntityFramework
Microsoft.AspNet.Identity.EntityFramework.Store<>.GetByID is looking for FindAsync<> in System.Data.Entity.DbSetExtensions.
Seems to be related to the change in work item 1368
STACK TRACE
[TypeLoadException: Could not load type 'System.Data.Entity.DbSetExtensions' from assembly 'EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.]
Microsoft.AspNet.Identity.EntityFramework.Store`1.GetByID(Object id) +0
Microsoft.AspNet.Identity.EntityFramework.<Find>d__c.MoveNext() +126
Comments: The refresh of the ASP.NET Identity Framework I mentioned before is now live in NuGet. http://www.nuget.org/packages/Microsoft.AspNet.Identity.EntityFramework/1.0.0-rc1
