As noted by Marie Hagman on the Product Feedback Center blog back in November, we have been working on improving the Product Feedback Center.
Microsoft Connect (connect.microsoft.com) is building the next version of the Product Feedback Center and integrating it with other tools to provide a better, more consistent and more unified feedback experience.
The Product Feedback Center is now part of Microsoft Connect. The Connect Introduction will give you an overview of what this new site can do for you. Like any move, we still have boxes to unpack. The Visual Studio and .NET Framework data will be available soon.
