I want to put together a Wednesday night talk, but I’ve dabbled in so much technology recently that I’m having trouble deciding on a topic. Here are the topics I’m thinking about so please let me know which ones you prefer:

Windows Presentation Foundation Fundamentals – How to get started with WPF
Windows Communication Foundation – Why is it better/different than ASP.Net, WSE, Remoting, etc?
Linq and C# 3.0 – MS finally brings OO persistence support to the table
Databinding in Windows Presentation Foundation – How to get your data onto the screen in an easy way
