Error when trying to Add-Migration in EF Code First Migrations–Alpha 3

Posted on 26 September 2011 and tagged with , 0 comments

Getting an exception like the below one when trying to add a migration with the shiny new Alpha 3 of migrations?

Add-Migration : Could not load type 'System.Data.Entity.Infrastructure.DbContextInfo' 
	from assembly 'EntityFramework, Version=4.1.0.0, 
	Culture=neutral, PublicKeyToken=b77a5c561934e089'.

At line:1 char:16

+ add-migration <<<<
   + CategoryInfo          : NotSpecified: (:) [Add-Migration], TypeLoadException
   + FullyQualifiedErrorId : System.TypeLoadException,System.Data.Entity.Migrations.AddMigrationCommand

The solution is to uninstall Microsoft ADO.NET Entity Framework 4.1 RC. To be on safe side, restart Visual Studio after the uninstallation.
