Using the WPF runtime SDK v 10.2.6
I have a ServiceFeatureTable, and I'm adding new poly line features to it. When I was adding poly lines with only the X and Y assigned to the MapPoint values, everything worked great.
Now I need to set the M value on the MapPoint in the poly line. Unfortunately, every time I call AddAsync, it gives me an exception "The shape must not have a M value. : ".
I've looked in my map, and it says that the layer I'm referencing supports M values.
Does anyone know how to solve this particular problem?
