Entity Framework connection string not from config

Question

public class Context : DbContext
{
    public Context(string connString) : base(connString) 
    {
        Database.SetInitializer(new MyContextInitializer());
    }

I suggest you to use always the EntityConnectionStringBuilder (System.Data.EntityClient):

EntityConnectionStringBuilder ecsb = new EntityConnectionStringBuilder();
ecsb.Provider = "System.Data.SqlServerCe.4.0";
ecsb.Metadata = "..."; // your metadata
ecsb.ProviderConnectionString = "Data Source=D:\\Context.sdf";

then you can generate the connection string in a simple way:

Context db = new Context(ecsb.ToString());

UPDATE:

Try to create the EntityConnection, then pass it to the context, instead of connection:

EntityConnection conn = new EntityConnection(ecsb.ToString());
Context db = new Context(conn);

Anyway, where is the metadata? It's required by the EntityConnection!
