Using DevForce with windows service

We're evaluating DevForce/Cocktail and have found it works great with WCF. Our application has a number of windows services and we've been unable to get it to work.

Does DevForce work with Windows Services? I could not find any examples in the documentation. Here is the sample code. All the MEF instantiations work correctly. However, the application hangs when trying to retrieve from the database. I have tried various things:

- Invoking the myService.ProcessRequests using a TaskFactory.StartNew
- Invoking the ProcessRequests from a Timer.Elapsed event

In all cases, the application hangs at the DB call. What do I do to fix this?

Thanks!
