This library is a .NET wrapper for the Google Maps API. It will allow you to query Google Maps for geocoding, directions, elevation, or places and will show you results on a static map. The documentation includes more information and code samples. This unofficial library is authored by Maxim Novak and licensed by the OSI BSD-2-Clause license.
Given the increasing popularity of mobile devices such as the iPhone and Android devices (both of which include full browsers), it should come as no surprise that developers have begun to leverage the various APIs out there to provide mobile mashups that can be implemented without targeting a specific platform or SDK.
