I needed to debug Windows Services. But I didn't like  suggested in multiple articles Debugger.Launch.

 

Thanks to post "Debugging Windows Services is a Pain" (and article CodeProject: Debugging Windows Services under Visual Studio .NET)

I was able

1. To download Service Debugging Helper (Binary) (or Service Debugging Helper (Binary + Source))

2. Add in my service project a Reference to AndersonImes.ServiceProcess.dll

3. Change in the Main() function

//ServiceBase.Run(ServicesToRun);
ServicesLoader.StartServices(ServicesToRun,true);

Note that  AutoStart boolean second parameter is very convenient for immediate start of debugging, in particular if you have only one service.

 

And all VS debugging features, including F5 and Edit&Continue are available.
