Prism with WCF services - are they always async?
===

I have started to build a WPF application in MVVM architecture (using Prism infrastructure).

I need the WPF application to connect to several different WCF services.

I am a bit puzzled, because I could not find any samples of such behavior on the net.

I have found some Silverlight+Prism samples that connect to WCF services, but they **always** do so asynchronously.

Is there a reason for this ? (my services are all 'sync').
