Nullability of reference types in type of parameter 'other' of 'int SlidePartData<T>.CompareTo(SlidePartData<T> other)' doesn't match implicitly implemented member 'int IComparable<SlidePartData<T>>.CompareTo(SlidePartData<T>? other)' (possibly because of nullability attributes).

Nullability of type of parameter 'obj' doesn't match overridden member (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'other' doesn't match implemented member 'int IComparable<Property>.CompareTo(Property? other)' (possibly because of nullability attributes).

Nullability of type of parameter 'obj' doesn't match overridden member (possibly because of nullability attributes).

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