Nuget package versioning or Entity Framework versioning?

Question

To create the project I am using the CODE-FIRST methodology, but to do some tests in the bank I had to do a Seeding Service (populate the database directly from the code ) for this I had to make some adjustments, since then I can not create a new controller.

measures already taken:

• I’m back to all settings (( but I’m not back in git versioning)).
• I changed the versions of the Entity Framework.
• I changed the versions of the Nuget packages.
• I changed the versions of the database. None of the above alternatives have solved the problems.

error message attached.

Specifications: Entity Framework: 2.1
