The Beta 1 .NET Framework 2.0 SDK and redistributable are available for download. You can find them here: http://lab.msdn.microsoft.com/vs2005/downloads/default.aspx
As always, let us know if there are any problems, bugs or things that just bug the heck out of you about the new SDK.
We've integrated the samples with the documentation; this allows you to search the samples while cruising the docs. You can still copy the samples into your file system as well.
