Hi, I need to draw a simple circle on the map and I need it to be perfect round (symmetric) on all places on the map, meaning the projection should not be taken into account.
Is it possible?
thanks
You can use geometry engines’ buffer method to do so: https://developers.arcgis.com/net/api-reference/api/net/Esri.ArcGISRuntime/Esri.ArcGISRuntime.Geometry.GeometryEngine.Buffer.html
just buffer a point that is in the same spatial reference as the map and it will be perfectly round. If you want perfectly round in the real world (which would likely look distorted in the map, use the BufferGeodesic method instead)

Tissot's indicatrix helps illustrate map projection distortion
might suggest that that will be a challenge until you specify the overage you intend (global vs local) and whether the circles need to have the same area.
perhaps you could provide more constraints
