I am trying to use ADO.Net Codefirst feature of latest Entity Framework 4.0. As part of that I have installed Entity Framework CTP 4 from Microsft and using Scott\'s tutorial t
The blogpost mentions the assembly:
The DbContext and DbSet classes used above are provided as part of the EF4 Code-First library. You’ll need to add a reference to the System.Data.Entity.CTP assembly that is installed into the \Program Files\Microsoft ADO.NET Entity Framework Feature CTP4\Binaries directory to reference these classes. You’ll also want to add a “using System.Data.Entity” namespace statement at the top of your “NerdDinners” class file.
However I do believe the new CTP5 includes some changes to codefirst, so I would suggest to take a look at that one instead.
