There was a problem hiding this comment. To make this example easier to follow, just There was a problem hiding this comment. The only thing that happens is Sandcastle gets stuck on the loading screen if returning early. I think it's preferable to try to avoid that, but maybe it doesn't matter if the demo wouldn't work anyways.
