I'm sure I'm missing something very simple.  I have an app that is using the world street map as its background layer.  This places my map in Web Mercator Auxiliary Sphere (WKID 102100).  I have my own dynamic tile layer service over top of that.

I want to add a graphic to the map, but the coordinates are in decimal degrees (WGS84).

Other times, i need to get the decimal degrees that the user is interacting with the map at.

How do i convert between the meters and decimal degree units in windows phone?
