* Status of the various pieces of the class library You can browse the status of the class library and see who has registered to work on what parts of the system. These list work-in-progress components currently. Browse the current status. You can also download the XML maintainers file that contains the actual maintainers list. You can also download the master Class Status XML file. * List of not-implemented classes These classes are only classes pending from the CORLIB assembly other assemblies are not yet listed. We are going to be working on an improved status display for pending classes. Please bear with us in the meantime. This is a list of pending classes, and links to their documentation on MSDN.Microsoft.com
