As Introducted in previous entry, the Microsoft Online technical forum support team is building a code sample framework including many useful code that cover most of the development technologies of Microsoft. You can get the All-In-One Code Framework at the following site:

http://cfx.codeplex.com

 Also, for Chinese users, there is a dedicated localized project for it: 

http://cfxchs.codeplex.com

 In addition, to provide better user experience and guide on the sample code, there will publish kb articles associated with some of the samples in the code framework:

Just enjoy it!
