OnGui doesn't work

Hi, I’m tryng to use the GUI but seems everything changed, I tried to add a simple button as a text, and MonoDevelop doesn’t show me any commands

alt text

I can’t get any references for any types of GUI, I tried GUI.Label GUI.Box etc. and nothing, I am doing something wrong?

This is because you named your class GUI. And having nothing inside it (except a private function) it doesn’t show anything. Rename your class to get the GUI library functionality.

going by the title of the post its OnGUI not OnGui
