Crash Recovery in Application

Question

What's the best way (standard solution maybe) to build crash recovery into my application so it can automatically restart on any kind of crash.

tnx.

It is in general better not to do this, there's nothing pretty about a process that constantly starts and immediately crashes again with the user helplessly looking at the carnage. But I can only hand you the bullets, aiming the gun at your foot is up to you. You'll need code like this:

    static void Main(string[] args) {
        AppDomain.CurrentDomain.UnhandledException += ReportAndRestart;
        // etc..
    }

    static void ReportAndRestart(object sender, UnhandledExceptionEventArgs e) {
        string info = e.ExceptionObject.ToString();
        // Log or display info 
        //...
        // Let the user know you're restarting
        //...
        // And restart:
        System.Diagnostics.Process.Start(
            System.Reflection.Assembly.GetEntryAssembly().Location,
            string.Join(" ", Environment.GetCommandLineArgs()));
        Environment.Exit(1);
    }
}

Beware that I took a shortcut on the command line arguments. They should be quoted if they contain a path to a file that contains spaces. Don't take shortcuts on the code you're supposed to put in the ellipsis.
