First thoughts on VS2010
Very impressed so far,
Liked the installed process, smooth even with the reboot. Liked the C#/C++ customization option. I don't do C++ anymore, so that was welcome. It also handled the SQL Server / Windows 7 compatability issues well.
Code Editor is very speedy for a beta release. Feels slightly better than the VS2008 experience, liking it so far but only written a few classes in it so not a fair test yet.
The WPF design environment still feels a little clunky and slow to me, but not as bad as VS2008. When I get around to doing some more complicated forms I'll have a better opinion probably.
Architecure Explorer is wonderful, looking forward to seeing what is makes of one of my larger projects.
My biggest cheer of the night was that ASP.NET didn't mangle my control ID's.
