In your Installer class, add a handler for the AfterInstall event. You can then call the ServiceController in the event handler to start the service.
using System.ServiceProcess;
public ServiceInstaller()
{
//... Installer code here
this.AfterInstall += new InstallEventHandler(ServiceInstaller_AfterInstall);
}
void ServiceInstaller_AfterInstall(object sender, InstallEventArgs e)
{
ServiceInstaller serviceInstaller = (ServiceInstaller)sender;
using (ServiceController sc = new ServiceController(serviceInstaller.ServiceName))
{
sc.Start();
}
}
Now when you run InstallUtil on your installer, it will install and then start up the service automatically.
