-This is a test of creating a portable Hamlib GUI controller using dotnet and GTK
-Should be able to compile on Windows, Linux, and MacOS
-No guarantee this will go anywhere depending on ability to talk to Hamlib via C#
-
-On Windows
-dotnet new install GtkSharp.Template.CSharp
-dotnet build
-
-
-
-
-On Ubuntu I don't see the GtkSharp package -- but you can build the code generated on the Windows side.
-apt install dotnet-sdk-6.0
-dotnet build
-
-
-Note: On Windows you can create a skeleton GTK app 
-dotnet new gtkapp
