Could anybody explain difference? When during installation I install teamcity like service I see teamcity agent service running.
What if agent installed without "as service" checkbox? How it will works? does it mean that I should start service manualy and thats all?
If you install the TeamCity build agent as a service, then it will automatically start when the system starts.
If you do not, you will need to manually start it every time the system starts.
