MVC enable-migrations NOT FINDING CONTEXT IN ASSEMBLY

I have two models, one I created in Microsoft SQL Server.... and one I am attempting to manage user roles etc for the application.

I used an approach that considers the ApplicatonDBContext for registering, deleting users etc. I have added the code in the controller and in the AccountViewModels in order to create my views.

I now need to enable migrations to update the database, but an error in the Package Manager Console appears:

More than one context type was found in the assembly 'Greenwich_Placement'. To enable migrations for 'Greenwich_Placement.Models.ApplicationDbContext', use Enable-Migrations -ContextTypeName Greenwich_Placement.Models.ApplicationDbContext. To enable migrations for 'Greenwich_Placement.Models.PlacementEntities', use Enable-Migrations -ContextTypeName Greenwich_Placement.Models.PlacementEntities.

So I use the command:

use Enable-Migrations -ContextTypeName Greenwich_Placement.Models.ApplicationDbContext

This error now appears:

The context type 'Greenwich_Placement.Models.ApplicationDbContext.' was not found in the assembly 'Greenwich_Placement'.

Thanks

I ran into the same problem today. When I enabled migrations, I copied from the output given in the "More than one context" error:

PM> Enable-Migrations -ContextTypeName MyPoject.Models.ApplicationDbContext.

and naturally, received the error

The context type 'MyPoject.Models.ApplicationDbContext.' was not found in the assembly 'MyPoject'.

Then I realized that there was a period at the end of ApplicationDbContext. When I removed it the migration worked fine:

PM> Enable-Migrations -ContextTypeName MyPoject.Models.ApplicationDbContext

Hope your issue is as simple/stupid as mine was!
