Nullability of reference types in type of parameter 'other' of 'bool DGMLNode.Equals(DGMLNode other)' doesn't match implicitly implemented member 'bool IEquatable<DGMLNode>.Equals(DGMLNode? other)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'sender' of 'void Program.myHandler(object sender, ConsoleCancelEventArgs args)' doesn't match the target delegate 'ConsoleCancelEventHandler' (possibly because of nullability attributes).
