Async Calls to Entity Framework

Anyo开发者_如何学Gone found a good way to make asynchronous calls to the db via entity framework? Use background worker thread? This is a WPF application.

I know in RIA services there is a loadcompleted event that does not seem to exist in entity framework's object context.

Thanks!

I've written a blog post about async calls via commanding in a WPF application

At work I use the same technique and do calls to DB (EF4).

Is this useful, or are you asking about more entity framework-specific async methods?
