I'm trying to cast from a SpatialQueryFilter up to a QueryFilter:
var spatialQueryFilter = new SpatialQueryFilter();
QueryFilter queryFilter = spatialQueryFilter;
However, the result type of the implicit cast for queryFilter is still SpatialQueryFilter. Casting (explicitly) the other way around does not work either.
Ultimately I want to pass either a QueryFilter or its SpatialQueryFilter subclass into FeatureLayer.FeatureTable.QueyAsync(QueryFilter). Without being able to cast a SpatialQueryFilter to a QueryFilter, QueryAsync always returns no results because the Geometry property is null. I understand there are workarounds for this, but am wondering why the casts aren't working?
