My congratulations to the .Net community and all .Net professionals: .Net Framework 4.0 Beta 1 and Visual Studio 2010 Beta 1 are available for download!
There are a couple of very useful links to read more about new look and new features of these incredible products form Jason Zanders’s (who is actually the General Manager for the Visual Studio team in Microsoft) blog:
VS2010: On Triangles and Performance
Announcing VS2010 / .NET Framework 4.0 Beta 1!
General Download of VS2010 / .NET Framework 4.0 Beta 1
.Net Framework and Visual Studio are the key products for the Microsoft Development Division, so you can hear much buzz around this beta on the pages of other Microsoft managers' blogs.
E.g. VS 2010 Extensibility featured on Scott Hansleman's blog:
Demo Dashboard and IDE Extensions - Whirlwind Tour around .NET 4 (and Visual Studio 2010) Beta 1
And Visual Studio 2010 SDK also already comes in Beta 1, you can find download link at the VSX Team Blog:
Announcing the Visual Studio 2010 SDK Beta 1
Extensibility features are my favorite because I am a part of Extensibility team (Extension Manager and VS SDK are those VS 2010 features which I worked on).
