Multiple Contexts Migrations Entity Framework

Question

I have several projects and each project has a context.
I would like to know, how to use the Migrations to update and generate only one database of these various contexts?

Answer 1

Multiple contexts are useful for structuring/isolating project areas; obviously this increases complexity. Then you can create each context by pointing to the same basis and perform the work normally.

Answer 2

One differential of EF6 is that it was released with the functionality to support multiple contexts. I found some answers to your problem :

Answer 3

You create only ONE connection, and use it for your project. So:

Context contexto = new Context();   <----(cria uma conexao)

ProjetoRepository nomeRepositorio = new ProjetoRepository (contexto);
(ProjetoRepository usando a conexao "contexto ")

OutroProjetoRepository nomeOutroReposito = new OutroProjetoRepository (contexto);
(OutroProjetoRepository usando a mesma conexao "contexto ")

Answer 4

Since each context is a completely different instance I believe that this is not possible. Unless you create a context that manages all contexts and encompasses in one.
