WCF Service Self Hosting Trouble


I'm trying to host a WCF Service inside a Windows Service which I am starting through a console app. Each service is its own project as is the console app. I've copied the app.config from the WCF Service library into the app.config of the console app, but I keep getting "Service has zero application endpoints...". I've read in a few places that the error means my type references are not fully qualified, but I've double (triple, quadruple...) checked that. And I'm pretty sure I have an app.config. There are 3 exes in my debug directory: Console App, Console App vshost, Win Service. The Win Service didn't have an app.config, so I tried copying its app.config in case it was looking for it, but no luck. I also checked to make sure the configs were named correctly (<program>.exe.config).

Here's what I'm using. My console app creates an instance of JobSchdeuler and calls JobSchedulerConsoleStart.

Host Code:

public partial class JobScheduler : ServiceBase
{
    ServiceHost jobServiceHost = null;

    public JobScheduler()
    {
        ServiceName = "JobSchedulerService";
        InitializeComponent();
    }

    #region Service Init/Uninit

    /// <summary>
    /// OnStart
    /// </summary>
    /// <param name="args"></param>
    protected override void OnStart(string[] args)
    {
        if (jobServiceHost != null)
        {
            jobServiceHost.Close();
        }

        jobServiceHost = new ServiceHost(typeof(JobSchedulerWCF.JobService));

        jobServiceHost.Open();
    }

    /// <summary>
    /// OnStop
    /// </summary>
    protected override void OnStop()
    {
        if (jobServiceHost != null)
        {
            jobServiceHost.Close();
            jobServiceHost = null;
        }
    }

    #endregion

    #region Debugging

    public void JobSchedulerConsoleStart()
    {
        this.OnStart(null);
        Console.WriteLine("Service Started.");

        ProcessInput();

        Console.WriteLine("Service Stopped.");
        this.OnStop();
    }

    private void ProcessInput()
    {
        Console.WriteLine("Press any key to quit...");
        Console.ReadKey();
    }

    #endregion
}

Solution

  • I never got to the bottom of this. There was something slightly off in the config/project. I rebuilt the solution and the problem went away.
