MapView crashes while rendering random geometries

Question

Some time ago, I asked this question on Stackoverflow. Sadly, I didn't get an answer yet. For convenience, I provide the text of the question here again (better formatting on Stackoverflow). Hopefully, someone can help me. I am using the Esri ArcGISRuntime for WPF SDK. When I add a specific geometry to a graphics layer the runtime throws an exception: System.Exception was unhandled HResult=-2146233088 Message=Geometry is corrupted and can not be used. :

problem is with this geometry? Is this a bug with the ArcGIS runtime, or do I need to take some special care when creating geometries? (This specific geometry is the result of Unioning multiple smaller geometries using GeoAPI.)

MathiasBecher · Answer

After further investigation, the problem seems to happen, when there are very small multipart geometry parts. The above geometry for example, contains a part with an area of about 0.6m².

But in my opinion the runtime should definitely not crash on encountering such a geometry.
