The MSDN Code Gallery is the latest developer portal offering for code snippets, samples, sample applications, and other great resources - including pages that describe samples, supporting docs with screenshots, and design documents.  We've also added hosted discussions about the code samples, sample projects or other resources that have been added to the gallery.  The MSDN Code Gallery is open to everyone to contribute to and it is a pure storage site with no project management capabilities so If you need to manage a live code project and collaborate with others on it, head over to CodePlex, another offering that we provide for open source project hosting.
