As stated above, I no longer have a crashing issue (that was a different issue).  I have now found that the map is not displaying at all and that there are issues when following this tutorial, due to two end points in the ServiceClient references.  I specify the basicHTTP one, and things seem to work, but no map is displayed.  The callback occurs, but following that, nothing is displayed on the actual control.

I have managed to get it working now.  It appears that the Bing Maps credentials were doing some funny things.

My issue now is that the MapNavigationPane does not appear to be doing anything.  I've removed the InitializeMapCoordinates() code so that nothing is hard-set.

The fact that the MapNavigationPane's not working as intended is due to the removal of the InitializeMapCoordinates() function. It is needed to make a map with only Geo-Imagery datasource specified interactive (pannable, zoomable, etc.). However, if a shape file, for example, is added to the map, the function will no longer be necessary.

Hope that helps,

It seems to have problems with the IsAutoWorldRect = false; when I set it to true OR false, the map doesn't load.  When I comment it out the map loads... ideas?

Hi terinfire,

One of the things done in the InitMapCoordinates() function is changing map's WorldRect to a custom one. That's why the explicit setting of IsAutoWorldRect to false is needed. If this is omitted, the map still loads but it is not interactive.

Best regards,

I found the issue -- the WindowRect was set before the WorldRect.  So, for future note, anyone who is setting things up needs to do something like:

XamMap.WindowRect = XamMap.WorldRect = WorldRectYouCreated;
