I watched the latest webcast about VS 2008. MS seem to integrate some function which is currently provide by opensource into VS 2008. For example LINQ is similar with what currently NHibernate doing. VS team system will have more testing functions, that is what NUnit is doing now. Well, I am a kind of Mono person, I will continue those open source framework. Moreover, I am doing a lot of things in Java too. Those framework have Java version. This is good for me jumping between C# and Java.
