The MSDN Code Gallery (http://code.msdn.microsoft.com/) is now available as another resources that let you download and share sample applications, code snippets, and other resources with the developer community.

As said by Soma Somasegar: "The MSDN Code Gallery is a portal for snippets, samples and other resources.  In it you can find pages that describe samples and supporting documents including screenshots and design documents.  In addition, you will find hosted conversations about these samples, sample projects or other resources that have been provided to the community.  This destination is open to the entire community to contribute content to.".

BTW, CodePlex (http://www.codeplex.com/) is still alive and kicking!
