Microsoft has announced the availability of Visual Studio 2010 & .NET 4.0 beta 1 for MSDN subscribers starting this Monday, and for the public starting this Wednesday.
According to Kirill Osenkon, 95% of the planned functionality is already there. This new version of Visual Studio is WPF based. Among the many new features, one important addition is the inclusion of F# as a first class language targeting the .NET framework. More information on the new features are available on Jason Zander’s blog.
