I have 4 projects :
Toombu.Entities : all models are there
Toombu.DataAccess: Mapping, Repository and ToombuContext
Toombu.Logique : Logic of my application
Thanks for the suggestions, I solved the problem by combining all the solutions here. At first I created the DbContext Model:
public class MyDbContext: DbContext
{
public MyDbContext()
{
}
}
After creating the dbcontext class, I ran the enable-migration command with the project Name: enable-migrations -ProjectName YourProjectName
