Longhorn Beta & Whidbey
From the Longhorn newsgroups, I just found out from Ed Kaim that “The plan of record is to have a corresponding build of VS for future Longhorn releases”. This includes the forthcoming Longhorn Beta. That's great news in my books - I don't mind building Longhorn apps using MSBuild (the current WinHEC build doesn't support any version of Whidbey - unless you hack the MSI file) but using a new VS build on a fresh new version of Longhorn will definitely be treat.
