CodeFx

Looking for some fully detailed examples of how to get the most out of Microsoft development technologies?  the guys over at CodeFx have exactly the solution you�re looking for!  CodeFx is written by Microsoft Support Engineers based on the most common scenario-based questions they get asked about developing with Microsoft technology.  From the CodeFx web site:

All-In-One Code Framework code-name CodeFx delineates the framework and skeleton of most Microsoft development techniques (e.g. COM, Data Access, IPC) using typical sample codes in different programming languages (e.g. Visual C#, VB.NET, Visual C++). For instance, the code example ATLDllCOMServer shows the skeleton of an ATL in-process COM server as its name implies. Each example is elaborately selected, composed, and documented to demonstrate one frequently-asked, tested or used scenario based on our experience as support engineers. If you are a software developer, you can fill the skeleton with blood, muscle and soul. If you are a software tester or a support engineer like us, you may extend the sample codes a little to fit your specific test scenario or refer your customer to this project if the customer’s question coincides with what we collected.

As of July 30th, 2009, there were over 200 samples in the download, and they said they are averaging about 6 new samples per week.  I downloaded and looked at a couple of the samples, and they look really well done � well documented, typical scenarios in both C# and VB.NET that all developers can relate to.
