Hi, I have very simple application just in the body of Main method. I have tried to find out different ways of ending the app except for Environment.Exit() but I entirely forgot I can just call return. Is it correct to use it for ending the app if it just run in Main method? I cannot see any problem but I want to learn as much as I can. Thanks

Right, sounds like you're on the right track. It's not clear if you're running a console application, and this code should help highlight.
static void Main(string[] args)
{
bool keepRunning = true;
int x = 0;
while (keepRunning)
{
//at some point, flip keepRunning to fall out of the while loop
if (moon.Color == Blue)
keepRunning = false;
if (x > 0) //or some other condition
return;
}
//naturally will fall out of the Main() and terminate the program
}

If you're exiting out due to an error, you really should use Environment.Exit with a non-zero argument... documenting what type of error returns which exit code is a good idea, too.
Otherwise, it should be OK to just return... but it's really a stylistic choice.

You can also declare `Main` to return `int`, and return your exit code. You don't have to call `Environment.Exit`.

@PDaddy: I wasn't aware that C# let you do that. Whoops.
