 Handling it is done as follows (on any node):

+ .. code-tab:: gdscript GDScript
 
     func _notification(what):
         if what == MainLoop.NOTIFICATION_WM_QUIT_REQUEST:
             get_tree().quit() # default behavior

 When developing mobile apps, quitting is not desired unless the user is
 on the main screen, so the behavior can be changed.
 
 It is important to note that by default, Godot apps have the built-in
 behavior to quit when quit is requested, this can be changed:
 
-::
+.. tabs::
+ .. code-tab:: gdscript GDScript
 
     get_tree().set_auto_accept_quit(false)
+
+ .. code-tab:: csharp
+
+    GetTree().SetAutoAcceptQuit(false);
