I'm pleased to let you all know that Microsoft released the first beta version of the next version of Visual Studio, Visual Studio Team System and Visual Studio Team Foundation Server. This of course also includes the next version of the .NET Framework and most of the new BCL features we've been blogging about in the last few months.

A note about BigInteger:
After releasing the BigInteger type in earlier CTPs we have received some good and constructive feedback from customers and partners that are interested in extended numerical types. We have learned that there are some potential improvements that we can make to this type to better serve their needs. As such, we decided to remove BigInteger from the Beta 1 release of Orcas so that we can address these issues and concerns. We would ask that you let us know if and how this affects you and what you would expect in a BigInteger class.
