How do I inject a connection string into an instance of IDbContextFactory?

Question

I\'m using Entity Framework 5 with Code First Migrations. I have a DataStore class which derives from DbContext:

public class DataS         


        

Answer 1

For those for whom upgrading to Entity Framework 6 is viable, there's a new overload of the migration initialization that makes this much easier:

    // Parameters:
    //   useSuppliedContext:
    //     If set to true the initializer is run using the connection information from the
    //     context that triggered initialization. Otherwise, the connection information
    //     will be taken from a context constructed using the default constructor or registered
    //     factory if applicable.
    public MigrateDatabaseToLatestVersion(bool useSuppliedContext);

Using this, you can run migrations with an injected DbContext as follows:

Database.SetInitializer(new MigrateDatabaseToLatestVersion(useSuppliedContext: true));

using (var context = kernel.Get())
    context.Database.Initialize(false);
