EF 6 Enable-Migrations cannot find context

I am trying to configure the first migrations of EF code to EF 6.1.3-.NET 4.5.

There are several projects in my solution, the launch project is Songbirds.Web . I created a project called Songbirds.Dal.EntityFramework to contain my repositories, database context, and migrations.

I created my context class:

 namespace Songbirds.Dal.EntityFramework { public class SongbirdsDbContext : IdentityDbContext<ApplicationUser>, IUnitOfWork { public SongbirdsDbContext() : this("name=SongbirdsDBContext") { } ... } }

The whole solution is built correctly, without errors.

I go into the Project Manager console and set the default project as Songbirds.Dal.EntityFramework and run the enable-migrations command, and I get the following error:

 PM> enable-migrations No context type was found in the assembly 'Songbirds.Dal.EntityFramework'.

I tried to explicitly specify the context type with the following result:

 PM> enable-migrations -ContextTypeName Songbirds.Dal.EntityFramework.SongbirdsDbContext The context type 'Songbirds.Dal.EntityFramework.SongbirdsDbContext' was not found in the assembly 'Songbirds.Dal.EntityFramework'.

SongbirdsDbContext is part of the Songbirds.Dal.EntityFramework project. Any ideas what I did wrong and why this does not recognize the context?

I think I found the answer through the trial version and the error. First, I changed the context class to inherit it from the DbContext class instead of IdentifyDbContext:

 public class SongbirdsDbContext : DbContext

And run the enable-migrations command to find the following error:

 Could not load file or assembly 'Microsoft.AspNet.Identity.Core, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

After adding the appropriate link to the required assembly, I was able to successfully complete the migration. I am not sure why inheritance from DbContext showed this error, while inheritance from IdentityDbContext was not.

Verify that the project is set to the project by default using the EF context.

Try to run

 enable-migrations -ContextTypeName Songbirds.Dal.EntityFramework

Adding .songBirdsContext to the end could be a problem.

I found a solution to this problem on my part in the fact that I just created a project, but have not yet created it. So building my project and re-executing the team worked
