About the Author

Microsoft All-In-One Code Framework delineates the framework and skeleton of Microsoft development techniques through typical sample codes in three popular programming languages (Visual C#, VB.NET, Visual C++). Each sample is elaborately selected, composed, and documented to demonstrate one frequently-asked, tested or used coding scenario based on our support experience in MSDN newsgroups and forums. 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.
