V12.1 - MapView.ToWorldCoordinate Returns Invalid X/Y

ThinkGeo UI for Desktop WPF

Thanks Dennis,
I think this is the same as the V12.1 - MapView_CurrentExtentChanged

The ToWorldCoordinate is depend on the current extent and map size etc.The very beginning the current extent may be some old value. So if you hookup the get current world coordinate to the mouse move event. After you zoom in/out the first few results may still based on the old extent. but soon it will get the new value base on the new extent.

Thanks
