When you open the Url, you will see the layer.
When using FromSyncImage or FromAsyncImage the layers will be shown as expected.
But when i use FromTileUri, no layers will be visible.

ACTUAL BEHAVIOR
TileLayer.FromTileUri doesn't show any Layer.
The generated Uris look like this: http://geodienste.bfn.de/ogc/wms/schutzgebiet?service=WMS&version=1.1.0&request=GetMap&typename=bfn_sch_wfs_schutzgebiet:Naturschutzgebiete&layers=Naturschutzgebiete&styles=&bbox=792499.109462544,6653078.94363616,802283.049085539,6662862.88325916&width=256&height=256&srs=EPSG:3857&format=image/png&transparent=true
