What's the best way to watchdog a desktop application?

Question

I need some way to monitor a desktop application and restart it if it dies.

Initially I assumed the best way would be to monitor/restart the process from a Windows

Answer 1

The watchdog process could make use of System.Diagnostics.Process to launch the application, use the WaitForExitMethod() and check the ExitCode property.

In response to the complaints over the question, I have had to use such a method when working with a legacy call center application over which I had no source control access.

EDIT:

For the host application you could use a .NET application of output type "Windows Application" and simply not have a form at all. For example:

namespace WindowsFormsApplication1
{
    static class Program
    {
        /// 

        /// The main entry point for the application.
        /// 
        [STAThread]
        static void Main()
        {
            var info = new ProcessStartInfo(@"calc.exe");
            var process = Process.Start(info);
            process.WaitForExit();
            MessageBox.Show("Hello World!");
        }
    }
}
