Get the Running Process Path

public static string GetProcessPath()

    // fix the path so that if running under the debugger we get the original file.
    string processName = Process.GetCurrentProcess().MainModule.FileName;
    int index = processName.IndexOf("vshost", StringComparison.Ordinal);

}

// Option 2:
// console program's can use:
private static string AppPath => Path.GetDirectoryName(Environment.GetCommandLineArgs()[0]);
