After looking around and playing with WCF for a while, it had come to my notice that all the examples that I could find were over complex, then I came across Ralf’s Sudelbücher blog entry for “A truely simple example to get started with WCF“, so simple, so to help you along here is the C# source code that I have written, with a few additions in that the solution also has a client console that calls the WCF application to show a true sence of what is happening.
