Debug Windows Service Running as Interactive Console Application

Before running in Visual Studio change the project output type from Windows Application to Console Application.  Below is sample Program.cs code to run interactively in Visual Studio.

using System;
using System.Reflection;
using System.ServiceProcess;
using System.Threading;

namespace DemoWindowsService
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        static void Main()
        {
            ServiceBase[] servicesToRun;
            servicesToRun = new ServiceBase[]
            {
                new DemoService()
            };
            if (Environment.UserInteractive) RunInteractive(servicesToRun);
            else ServiceBase.Run(servicesToRun);
        }

        static void RunInteractive(ServiceBase[] servicesToRun)
        {
            Console.WriteLine("Services running in interactive mode.");
            Console.WriteLine();

            MethodInfo onStartMethod = typeof(ServiceBase).GetMethod("OnStart",
                BindingFlags.Instance | BindingFlags.NonPublic);
            foreach (ServiceBase service in servicesToRun)
            {
                Console.Write("Starting {0}...", service.ServiceName);
                onStartMethod.Invoke(service, new object[] { new string[] { } });
                Console.Write("Started");
            }

            Console.WriteLine();
            Console.WriteLine();
            Console.WriteLine(
                "Press any key to stop the services and end the process...");
            Console.ReadKey();
            Console.WriteLine();

            MethodInfo onStopMethod = typeof(ServiceBase).GetMethod("OnStop",
                BindingFlags.Instance | BindingFlags.NonPublic);
            foreach (ServiceBase service in servicesToRun)
            {
                Console.Write("Stopping {0}...", service.ServiceName);
                onStopMethod.Invoke(service, null);
                Console.WriteLine("Stopped");
            }

            Console.WriteLine("All services stopped.");
            // Keep the console alive for a few seconds to allow the user to see the message.
            Thread.Sleep(5000);
        }
    }
}
