Question

I have a C# Application that has a GUI and has its output type set as Windows Application. I would also like to invoke it from the command line (via parameters) and thus it needs to also be a Console Application.

Is there a way to get my application to run both as a Windows Application and as a Console Application?
Is there a way to set this at run time or is it a compile time setting?

You can attach the console. Make the code in Program.cs look like this:

    [STAThread]
    static void Main(string[] args) {
        if (args.Length > 0) {
            AttachConsole(-1);
            Console.WriteLine("");
            Console.WriteLine("Running in console, press ENTER to continue");
            Console.ReadLine();
        }
        else {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }
    }
    [System.Runtime.InteropServices.DllImport("kernel32.dll")]
    private static extern bool AttachConsole(int pid);
