As I have mentioned before I am working on a book that covers Visual Studio 2010 and .NET 4.0.  So I have been playing with Visual Studio 2010 for quite a while now, and many of the common lines of feedback have been that the product is a great improvement in a lot of areas, however, there has been an overarching performance issue that has been plaguing various aspects of the new release.  Late yesterday Scott Guthrie from Microsoft blogged a Visual Studio 2010 and .NET 4 Update announcing that Microsoft is pushing the release date of Visual Studio 2010 and .NET 4 back "a few weeks" to allow for a public release candidate in the February 2010 time frame.

 Although I'm anxious to be able to use the new version of Visual Studio as some of the already existing performance improvements have been great.  Especially the "Reference Dialog Load Time" improvement, which is just amazing.  I'm glad to see that the feedback that all of the beta testers, MVP's and other people that have been testing and working with Visual Studio has been taken very seriously.  I think with the additional time, they are going to be able to deliver a product that is that much superior!
