Got up a little early today and had some time to mess around. I had been reading about Virtual Earth 3D, and decided to see if it the control could be added to a Winforms app. I found a rough how-to from this blog, and it took a little more meddling to get things working, but it definitely does work.
Since the SDK is not actually released yet, it's going to take some stumbling around the API to do useful stuff with it, but think about what this and SQL 2008 are going to allow us to build!
