Much later than I would have liked but the development tools for the .NET Framework 3.0 are now live on the web.  You can download it by going to http://www.Microsoft.com/downloads/details.aspx?FamilyId=935AABF9-D1D0-4FC9-B443-877D8EA6EAB8&displaylang=en.

 

Don't forget to download the .NET Framework 3.0 & Windows SDK first.
