Error in MapLocation class

public bool InRangeOf(MapLocation location, int range) { return DistanceTo(location.X, location.Y) <= range;

        }

In visual studio 2019 it says that: "The modifier 'public' is not valid for this term" Can someone explain? It seems to work for him in the video though

Sometimes the compiler doesn't notice an error until it gets to the following line. I'd look at the previous line, it may be something as simple as a missing semicolon.

If that's not it, please show more of the code (perhaps the entire module).

I think you're missing a bit of code, which overloads the DistanceTo method, with a single point. This is passed into the original method: 

public int DistanceTo(Point point)
        {
            return DistanceTo(point.X, point.Y);
        }
