You probably don't want to create multiple EntityManagers in your application.  You probably want just one.  You could create a singleton class to do this.  If you do want to use multiple EntityManagers, consult the DevForce Resource Center.

In your samples for Silverlight, you show in the ViewModel class that you do the following
 
mgr = new NorthWindEntities();
 
I don't really want to do that in everyone of my ViewModel classes do I? Won't that hurt performance? Should I create a singleton class for this purpose or does it matter?
