I am currently using ESRI .NET WPF SDK v100.1.0.
I created a class that inherits from LocationDataSource, and within it I am using the inherited methods UpdateLocation() and UpdateHeading().
I set the LocationDisplay's DataSource to an instance of this class.
UpdateLocation() works and I can see my symbol on the map at the correct location.
However, UpdateHeading() doesn't seem to be updating the symbol and it is always facing North.
Please help. Thanks!
