Just in time for the PDC (Professional Developers Conference) 2008, there is a new Visual Studio 2010 and .NET Framework 4.0 CTP is available for download. Attendees of the PDC will receive a hard drive with the CTP as well as information around Windows Azure, Windows 7, and more.
In the CTP, its been configured with sample data and walk-thru scenarios to get up to speed with many of the highlighted features.
If you're interested in downloading the CTP, make sure you have a fast connection. Like all VSTS CTPs, the total download is about 8GB (made up of 11 files), and the expanded VPC is about 27 GB.
To get a good idea what you can expect to see in VSTS 2010, check out the videos that Brian Keller posted on Channel 9.
