WCF + LINQ?

In an n-tier application, is it possible to send objects created by LINQ between layers? More specifically, is it possible to send LINQ object via a WCF service? Well, the short answer is yes.

LINQ

Last night I attended a very informative talk hosted by sadeveloper.net. Armand explained in detail how LINQ works. Some very interesting subjects was touched on (ie. Lambda expressions, Anonymous types, Extension methods, etc.). The only subject that wasn't touched on was binding to WPF controls. I am hoping to post a little more on this subject in the near feature. I also lauched my first official open-source project today. Please note that the project is still in very early development but...
