When programming you will have to perform numerous NPE checks, in C# 6.0 Microsoft introduced monadic null checking. Although this is already some time available, I just found out.

So instead of doing this:

if (points != null) {
  var next = points.FirstOrDefault();
  if (next != null && next.X !=null) {
    return next.X;
  }
}
return -1

You can do this:

return points?.FirstOrDefault()?.X ?? -1;

After some time you are really starting to like it.
