Convert console application to windows service

Question

I have a console application which I am running SignalR with. I am attempting to convert it into a windows service application.

I simply swapped out the Main method with

static void Main()
{
    var servicesToRun = new ServiceBase[] 
    { 
        new MyService() 
    };
    ServiceBase.Run(servicesToRun);
}

and added a service class which is simply:

namespace Services
{
    partial class MyService : ServiceBase
    {
        IDisposable SignalR { get; set; }

        public MyService()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
            const string url = "https://localhost:8080";
            using (SignalR = WebApp.Start<Startup>(url))
            {
                          //TODO: Add Logging
            }
        }

        protected override void OnStop()
        {
            SignalR.Dispose();
        }
          }
}

But now when I try to run the installer I get the error:

Exception occurred while initializing the installation: System.BadImageFormatException: Could not load file or assembly 'file:///C:\Code \MyCode\Services\bin\Debug\MyService.exe' or one of its dependencies. A n attempt was made to load a program with an incorrect format..

Is there any easy way to debug this message? Or does anyone have any idea of what I may have missed?

Answer 1

How are you running the installation? I'd wager a guess that you're registering a 32-bit compiled application with the 64 bit installer or vice versa

In other words, running:

%windir%\Microsoft.NET\Framework\v4.0.30319\installutil.exe <My x64 DLL/EXE>

or:

%windir%\Microsoft.NET\Framework64\v4.0.30319\installutil.exe <My x86 DLL/EXE>
