Could anyone point me to a resource that explains WCF with pictures and simple code snippets. I am tired of googling and finding the same "ABC" articles in all search results.

Windows Communication Foundation (WCF) is a framework for building service-oriented applications. Using WCF, you can send data as asynchronous messages from one service endpoint to another. A service endpoint can be part of a continuously available service hosted by IIS, or it can be a service hosted in an application.
This hosting is very flexible and easy to use, but suitable only during development phases of a distributed application. IIS: When a WCF service is hosted in IIS the client can access the service over the internet.
As long as the Windows operating system continues to include . NET Framework, WCF will continue to function.
WCF is a very complex technology that in my opinion is very poorly documented. It is incredibly easy to get up and running with, but the performance tuning to run a large scale app can be incredibly complicated and a lot of trial and error. One day everything is working fine and then you find out that only a single Channel is kept waiting for a new connection and that there is a config setting that you need to adjust on a custom binding to allow more channels to be waiting so that calls don't fail inbetween when a channel is used and the next channel is spun up.
In general Nicholas Allen's blog is a gold mine of information. However Windbg has been my best friend in trying to explain some very bizarre behavior coming from WCF.
