Support .Net Core

Doing this would require the dotnet cli tools in the path.

Start by checking how this package exposes command-line tools in the Flatpak environment and whether the dotnet CLI tools can be made available in PATH. Done means .NET Core tooling can be invoked from Visual Studio Code; the issue names no files or tests, so the required packaging changes need investigation.
