In October, we shipped Beta 2 of Visual Studio 2010 and .NET Framework 4. Since then, we have received a lot of helpful, constructive feedback from you all. Thank you.
A lot of you have given us very positive feedback on the new capabilities of VS 2010 and .NET Framework 4 and are very happy with the breadth of value that we are poised to deliver in this release.
At the same time, you have also given us feedback around performance issues, specifically in a few key scenarios including virtual memory usage. As you may have seen, we significantly improved performance between Beta 1 and Beta 2. Based on what we’ve heard, we clearly needed to do more work. Over the last couple of months, our engineering team has been doing a push to improve performance. We have made significant progress in this space since Beta 2.
With these improvements in the product, we do want to make sure that they truly address the performance issues while continuing to maintain a high quality bar. As a result, we are going to extend the beta period by adding another interim checkpoint release, a Release Candidate with a broad “go live” license, which will be publicly available in the February 2010 timeframe.
Since the goal of the Release Candidate is to get more feedback from you, the team will need some time to react to that feedback before creating the final release build. We are therefore moving the launch of Visual Studio 2010 and .NET Framework 4 back a few weeks.
Please continue to send us your feedback. It truly has an impact on the product development process and helps us to deliver a high quality product.
