I have been using Visual Studio 2010 Beta 2 and TFS 2010. They are awesome!
VS2010 is going to be a great poroduct, when it goes RTM. I see a lot of effort on making may life as developer a lot more easy. The integration with Visual Studio Gallery is good (could be better, like allowing to search by cost of the extension, more a la site version). On the PDC 2009 MS that the free version of Code Rush will also be available for Vs2010 developers.
I will include some captures as soon as possible.
On the TFS 2010 side, it’s becoming a serious contender on his segment. Now with a native integration with project server, the managers can concentrate all the info in just a a tool and get an updated snapshoot on the project status every time they want.
Also the new compilation farms are nice. The compilation process is now Workflow based, so you can adjust the process with custom activities as you need. That and much more to come.
