I spent all day yesterday working with VS2010 RC. (MSDN Subscribers could download late on Monday. It becomes public today).
First impression: It is much faster, and more stable than the beta 2 build.
Caveats: It’s only been one day. If I were making a ship decision, I’d say VS2010 RC needs a lot more soak time.
I put VS2010 RC on the PDC Laptop. (The Windows Rating is a 3.2, due to the Windows Aero score). On that machine, the VS2010 Beta was rather painful. It worked, but I could type noticeably faster than VS2010 could display characters. Even worse, slewing characters would cause the display to fall more than a screen behind in drawing.
None of those effects occur in the the VS2010RC. (VS2010 RC uses the hardware rendering on this machine. See Jason Zander’s discussion of perf changes betwen B2 and the RC for more information.) I spent all day coding on the PDC laptop. It kept up during the entire day. Scrolling, slewing keys, intellisense. It’s downright zippy.
As an extra added bonus: The Add Reference dialog appears in a heartbeat.
As of now, I am doing all development in VS2010 RC.
