Entity Framework multiple projects with code first migrations

c# ef-migrations entity-framework entity-framework-6


I have a class library project named "Core" which defines CoreContext with properties for common classes:

public class CoreContext : DbContext
    public DbSet<User> Users { get; set; }
    public DbSet<Role> Roles { get; set; }
    public DbSet<UserContactInfo> UserContactInfos { get; set; }
    ... more common properties ...

Then I have multiple projects referencing the "Core" project and defining new Contexts inheriting CoreContext:


public class Project1Context : CoreContext
    public DbSet<Foo> Foos { get; set; } //object defined in Project1


public class Project2Context : CoreContext
    public DbSet<Bar> Bars { get; set; } //object defined in Project2

When I change something in Project1Context I create a new migration in Project1 which is OK, but if I change something in the Core project, lets say add property Company to UserContactInfo I will have to go to Project1 and Project2 and add new migration and I will end up with migrations related to the Core project in Project1 and Project2.

My question is: Is there a way I can keep the migrations for CoreContext in the Core project and Project1Context and Project2Context migrations to their corresponding project and automatically execute all migrations related to the project, so when I start Project1 it will run its own migrations and CoreContext migrations?

As clarification, I have separate databases for Project1 and Project2 and recently Updated EF to version 6.

Perhaps you could write your own sub class which inherits from MigrateDatabaseToLatestVersion?
