Modify Windows service registry key so that we can pass parameters.

ProjectInstaller.cs

        private void serviceInstaller1_AfterInstall(object sender, System.Configuration.Install.InstallEventArgs e)
        {
            try
            {
                RegistryKey servicesKey = Registry.LocalMachine.OpenSubKey(@"System\CurrentControlSet\Services\");
                RegistryKey serviceKey = servicesKey.OpenSubKey(serviceInstaller1.ServiceName, true);
                serviceKey.SetValue("ImagePath", (string)serviceKey.GetValue("ImagePath") + " dispatcher= " + Context.Parameters["dispatcher"]);
            }
            catch (System.Exception ex)
            {
                System.Console.WriteLine("Failed to update service");
            }
        }
