Can I use Bing Maps (Virtual Earth) within a Windows Forms or WPF Desktop Application?
As far as Licensing, you’ll need to contact Microsoft. The “Microsoft Virtual Earth Platform API Terms of Use” doesn’t really cover this specific usage scenario. Microsoft doesn’t have a Window Forms or WPF control that you can just drag onto a Window, but you could access the Web Service from your application or display the JavaScript Map Control within an embedded WebBrowser control.
