I'm working on SaaS application where each customer will have separate database. I store all database connection info in one central system database.
 
How do I "tell" EntityManager which connection string to use depending on parameter? In EF it's kind of easy, I just override constructor and build new Connection string.

I like it how you guys thought about everything. I found this example:
 
My question is.. Since I didn't find where it's referenced from. Do you use MEF to find interface? I'm little confused because this implementation just hangs in there and I don't see [Export] attribute on this custom class?

Hi katit;

Yes, that is correct. We use MEF to discover the IDataSourceKeyResolver interface as well as a bunch of others. Here's the list if you're interested.
