Wow- the long-awaited VS 2010 release has finally come! With .NET 4 built in, there are many exciting new possibilities with Visual Studio.

There are also quite a few enhancements in the "built on WPF" IDE. Auto completion of "switch on enum" expressions is one of my favorites. (See my PDC talk for more info on that - scan to about 40:20 to see the overview of switch auto-complete)

Since I worked on the new System.Device.Location API, I have plenty of ideas about location-aware apps I'd like to build, but with VS 2010, the sky is the limit...

What are you going to build?

Here's a link to the VS 2010 page showing improvements over previous versions:
