atialReference sr3857 = SpatialReferenceBuilder.CreateSpatialReference(3857); // Builder constructors need to run on the MCT. using (SpatialReferenceBuilder srBuilder = new SpatialReferenceBuilder(3857)) {     // do something with the builder     sr3857 = srBuilder.ToSpatialReference(); } ArcGIS.Core.Geometry.Polygon envPoly = null; Envelope mapExtent = (Envelope)GeometryEngine.Instance.Project(MapView.Active.Extent, sr3857);   private Envelope BuildEnvelope(MapPoint mapPt, Envelope inputEnvelope) {     EnvelopeBuilder envelopeBuilder = new EnvelopeBuilder(SpatialReferences.WebMercator);     envelopeBuilder.XMin = inputEnvelope.XMin;     envelopeBuilder.YMin = inputEnvelope.YMin;     envelopeBuilder.XMax = inputEnvelope.XMax;     envelopeBuilder.YMax = inputEnvelope.YMax;       return envelopeBuilder.ToGeometry(); } Envelope mapExtent = BuildEnvelope(MapView.Active.Extent)   Envelope mapExtent = EnvelopeBuilder.CreateEnvelope(MapView.Active.Extent, SpatialReferences.WebMercator);   Envelope mapExtent = EnvelopeBuilder.CreateEnvelope(MapView.Active.Extent, SpatialReferences.WebMercator);

Size mapSize = MapView.Active.GetViewSize();
MapPoint pt1 = MapView.Active.ClientToMap(new Point(0, 0));
MapPoint pt2 = MapView.Active.ClientToMap(new Point(mapSize.Width * scale, 0));
MapPoint pt3 = MapView.Active.ClientToMap(new Point(mapSize.Width * scale, mapSize.Height * scale));
MapPoint pt4 = MapView.Active.ClientToMap(new Point(0, mapSize.Height * scale));

Point mapClientPt = MapView.Active.MapToClient(screenMapPt);

bool ptIntersects = (mapClientPt.X >= 0) && (mapClientPt.Y >= 0) && (mapClientPt.X <= mapSize.Width * scale) && (mapClientPt.Y <= mapSize.Height * scale);

This produces the exact results that I am looking for.  Once I have the rectangle I can then check to see if the mouse intersects it or not.

Thanks again to the Esri ArcGIS Pro SDK team.
