if (region.Contains (x, y))
	return true;
return false;

converts to:

return region.Contains (x, y) ? true : false;

But it should be

return region.Contains (x, y);

the next one should be recognized by another issue - I've a redundant conditional operator for exactly this case.

I don't know if it's worth putting the logic in the replace with return fix - I'll look what r# does in that case :)

Yeah, the other issue did show up, it just seemed strange that the first issue created such obviously redundant code.
Comment 3 Mike Krüger 2013-08-22 08:55:05 UTC

But generally I don't think it's a good idea to let the code issues optimize the code to the end because I don't want that the user loses track of what's going on. Therefore it's often better to let it do step by step.

However in that special case I don't see any reason to generate the cond ? true : false branch. I hope nobody gets confused by this very simple case :)
