FPSProject Fake Error

I use VS2017

Study official tutorials FPSProject

but what’s this ???

This is just intelisense in Visual Studio thinking these are errors.
I pretty much ignore intelisense and only look at the output window after I’ve compiled, which shows the “real” errors.

You may want to ditch that poor Intellisense. VisualAssist is 100x better, faster and more accurate.
