[DOTNET] Problem running multiple services from single process

[David Glauser]

I'm trying to host two services in a single process, and cannot get the second to 
start. The first is a simple do-nothing service, and is there to make it easy to 
attach the debugger. After setting breakpoints, I can start the second and debug it. 
The relevant parts of my service class look like this.

in myservice.cs:

static void Main()
{
        System.ServiceProcess.ServiceBase[] ServicesToRun;

        // To run the debug service, uncomment the following code line and comment out 
the
        // line that runs only the main service.
        ServicesToRun = new System.ServiceProcess.ServiceBase[] {new MyService(), new 
DebugService()};
        //ServicesToRun = new System.ServiceProcess.ServiceBase[] { new MyService() };

        System.ServiceProcess.ServiceBase.Run(ServicesToRun);
}

private void InitializeComponent()
{
        this.ServiceName = "MyService";
}

in debugservice.cs:

private void InitializeComponent()
{
        components = new System.ComponentModel.Container();
        this.ServiceName = "DebugService";
}

and the installer has:

private void InitializeComponent()
{
        this.serviceProcessInstaller1 = new 
System.ServiceProcess.ServiceProcessInstaller();
        this.serviceInstaller1 = new System.ServiceProcess.ServiceInstaller();
        this.serviceInstaller2 = new System.ServiceProcess.ServiceInstaller();
        // 
        // serviceProcessInstaller1
        // 
        this.serviceProcessInstaller1.Account = 
System.ServiceProcess.ServiceAccount.LocalSystem;
        this.serviceProcessInstaller1.Password = null;
        this.serviceProcessInstaller1.Username = null;
        // 
        // serviceInstaller1
        // 
        this.serviceInstaller1.DisplayName = "Debug Service";
        this.serviceInstaller1.ServiceName = "DebugService";
        // 
        // serviceInstaller2
        // 
        this.serviceInstaller2.DisplayName = "MyService";
        this.serviceInstaller2.ServiceName = "MyService";
        // 
        // ProjectInstaller
        // 
        this.Installers.AddRange(new System.Configuration.Install.Installer[] {
                this.serviceProcessInstaller1,
                this.serviceInstaller1,
                this.serviceInstaller2});
}

The installation works. The debug service can be started. When I try to start the 
other service, I get

"Could not start the MyService service on Local Computer.
 Error 1083: The executable program that this service is configured to run in does not 
implement the service."


This is the error I would expect to see if the ServiceName property of the service 
does not match the ServiceInstaller's ServiceName property, but they DO match? Can 
someone tell me what I'm doing wrong?
