Windows .Net is not yet officially supported by TSM, though development is actively working on it--witness the .Net references in the v5.1.0 Windows doc that we didn't quite get removed when Microsoft slipped their GA date. As Mark Stapleton indicates it would hard to declare official certification on an operating system that has not reached release candidate status, let alone general public availability.
If you choose to try TSM on .Net you need to be aware that we have some open bugs with Microsoft in the area of system object backup that are being worked upon. Behavior and stability in that area of Windows .Net have been volatile in recent builds that we've obtained. We've not noted any problems with normal file backup/restore.
