From the page: "For those that have read some of my other CodeProject.com articles, you will probably know that I am not shy about trying out new technologies. One good thing about that is that I generally share what I learn right here and this article is one of the hardest ones I've done, IMHO. This article is about how to create a peer-to-peer chat application using Windows Communication Foundation (WCF) and also how to make it look nice using Windows Presentation Foundation (WPF).

When I first started reading about WCF, the first place I looked was the MSDN WCF Samples (which I read a lot), but they weren't that great.

From the page: "Changing a LINQ expression dynamically (at runtime) depending on the userâ€s input is one of the problems that are often discussed in forums and blogs. I know at least three solutions proposed by Tomas Petricek tomasp.net/blog/linq-expand.aspx [tomasp.net/blog/linq-expand.aspx] ), Joe Albahari albahari.com/nutshell/predicatebuilder.html [albahari.com/nutshell/predicatebuilder.html] ) and implemented in the DynamicQuery MS sample. In this article I want to show how rewrite rules can be defined as lambda expressions and used to transform expressions (queries). This technique may provide the following benefits: "
