map export without window in console application

Hello! My original application has an user interface, where I can load a background and draw polygons on top. The image export with

var stream = new Mapsui.Rendering.Skia.MapRenderer().RenderToBitmapStream(MyMapControl.Viewport, MyMapControl.Map.Layers, MyMapControl.Map.BackColor);

is working well.

Now I have the task to export the same image in a console application without user interface. I created Mapsui.Map MyMapControlMap = new Mapsui.Map(); (with two layers: 1at layer a png as background, 2nd layer polygons) Mapsui.Viewport MyMapControlViewport = new Mapsui.Viewport(); (with extent etc.) As soon as I try the export with the command:

var stream = new Mapsui.Rendering.Skia.MapRenderer().RenderToBitmapStream(MyMapControlViewport, MyMapControlMap.Layers, MyMapControlMap.BackColor);

it’s not working. It returns null, because probably the surface snapshot is not working. How can I create a stream of the map layers without a window?

I’m thankful for any advice! Thanksyou very much, Claudia

I reloaded all nuget packages and now all dependencies are working. Problem solved! Thanks!

Ah, I didn’t get this. Sorry for the wrong hint.
