Well if JasonZ can blog about it, I suppose that means I can too. 🙂
He talks about some changes in Beta 1 that were in response to customer feedback... that's always good. And, our focus on performance of VS 10. Also, Beta 1 is getting *very* close to releasing... Along with the product, we will be releasing a Beta of the VS SDK to help developers extend Visual Studio with new packages and extensions.
