I am migrating my project from sdk version 10.2.7 to version 100.5 (C# with WPF). We have several feature layer on a local maschine that we use in our actual application.
When I use the layer with the new sdk I can only see the label but not the symbol. On the server is version 10.6 installed. When I define an other symbol in the source code this symbol is shown on the map. I have attached the definition of the layer in json.
