Hello, I am trying to consume a WCF service in .NET 5.0, using dotnet-svcutil to generate .cs client class. When trying to run the tool, I get the following output in a terminal window:

Not sure, but there seems to be a problem with CustomBinding. Does anyone know why this happens, and how I can fix it. Any help is greatly appreciated!
