The Visual Studio team recently made a Beta 1 release of the next version of Visual Studio (codenamed "Orcas") available as a virtual machine. 

The download might scare you off, it's quite large!  But at least your system stays clean... 

Overview - Visual Studio Code Name “Orcas” delivers on Microsoft’s vision of smart client applications by enabling developers to rapidly create connected applications that deliver the highest quality rich user experiences. This new version enables any size organization to rapidly create more secure, manageable, and more reliable applications that take advantage of Windows Vista, 2007 Office System and the Web. By building these new types of applications, organizations will find it easier than ever before to capture and analyze information so that they can make effective business decisions.

This beta targets early adopters of the Microsoft technology, platform, and tools offerings. It enables developers to experience the upcoming toolset and underlying platform improvements. We designed this release to enable developers to try out new technology and product changes, but not to build production systems. This limitation is fully covered in the EULA that accompanies this beta.
