    Default Spatial Reference Conversion

    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?

    I believe this is the method you are looking for:

    There's also a more automated approach described in this blogpost (although it's probably overkill for this scenario and can have a slight impact on perf): http://blogs.esri.com/Dev/blogs/silv...cs-layers.aspx
