A short time ago I blogged about the announcement of the release of Visual Studio 2008 and Microsoft .NET Framework 3.5.
If you are looking for something to actually run, the VSTS2008 90-day trial is available for download here.
All 3.9Gb of it. Phew! Don't try that over dial-up or else (apparently) it will take you 159 hours 21 minutes.
