An easier way to debug windows services

Have you got tired of attaching the Visual Studio debugger to the service application? I got the solution just for you! It’s a small helper class containing a static method which you need to invoke.

public static void Main(string[] argv)

{

    // just include this check, "Service1" is the name of your service class.

    if (WindowsServiceHelper.RunAsConsoleIfRequested<Service1>())

        return;

    // all other code

}

Then go to project properties, the “Debug” tab and add “-console” as Command Arguments.

How to configure Visual Studio

That’s it. What I do is simply allocate a console using the winapi and then invoke (through reflection) the properprotected methods in your service class.

Source code for the helper class:

public static class WindowsServiceHelper

{

    [DllImport("kernel32")]

    static extern bool AllocConsole();

    public static bool RunAsConsoleIfRequested<t>() where T : ServiceBase, new()

    {

        if (!Environment.CommandLine.Contains("-console"))

            return false;

        var args = Environment.GetCommandLineArgs().Where

			(name => name != "-console").ToArray();

        AllocConsole();

        var service = new T();

        var onstart = service.GetType().GetMethod("OnStart",

		BindingFlags.Instance | BindingFlags.NonPublic);

        onstart.Invoke(service, new object[] {args});

        Console.WriteLine("Your service named '" + service.GetType().FullName +

			"' is up and running.\r\nPress 'ENTER' to stop it.");

        Console.ReadLine();

        var onstop = service.GetType().GetMethod("OnStop",

		BindingFlags.Instance | BindingFlags.NonPublic);

        onstop.Invoke(service, null);

        return true;

    }

}
