I contacted with Google and had been answered the following:
"as far as I understand, is allowed to use Google maps API over a MS platform.
So as I understand if we can implement a provider with RadMap we can do it... right? (besides licensing... that is another war)
I had to check that Google wouldn't mind on having Google Maps on Silverlight.
And that is positive. If I manage to have a way on doing it on Silverlight I can do it.

Now it would be good some help on creating a provider for Google Maps. Can I have some help, please?
Thanks for any comment.
