November CTP of .NET Whidbey available on MSDN for subscribers
If you are an MSDN subscriber, the November CTP of .NET Whidbey (build 41202) is available. This is different from the December CTP of Sql Server, which uses build 40903.27 of .NET. Don't try and install the the two on the same machine. It won't work. Don't even try it. Use separate machines or VPC/VMWare.
