General Download of VS2010 / .NET Framework 4.0 Beta 1
Great news.
Beta 1, which has been available to MSDN subscribers since Monday, is now available to everyone.
You can download the following installations from the Visual Studio 2010 and .NET Framework 4 Beta Homepage:
Visual Studio Team System 2010 Team Suite Beta 1
Visual Studio Team Foundation Server 2010 Beta 1
Visual Studio 2010 Professional Beta 1
.NET Framework 4 Beta 1
You can find a detailed walk through of Beta 1 here (by Jason Zander).
This beta does have full setup available so you can provision it yourself. The product is designed to work cleanly with VS2008, however like any pre-release software you should be careful about using the product on your main machine.
If you want to give Microsoft feedbacks, do it through Visual Studio 2010 / .NET Framework 4 Beta 1 Forums.
