I'm finally excited to share that .NET Framework 4.0 Beta1 and Visual Studio 2010 Beta1 is being released this week! After having kept it low key and quiet for so long, and a limited distribution at the PDC last year, it is great that this week, Beta1 will be available more generally. Today, Beta1 bits were released to MSDN customers and Beta1 documentation went live on MSDN. In addition, forums have been created for soliciting feedback. On May 20th, Wednesday, Beta1 will be available on MSDN download center for everyone. Here is the VS 2010 page.
Me and my team definitely look forward to hearing all the feedback you have on Windows Workflow Foundation in .NET 4.0.
