Custom attribute that, when added to a field, property or parameter, throws an ArgumentException if the target is assigned an empty value. The custom attributes can be added to locations of type string (where empty means zero characters), or ICollection, ICollection<T>, IReadOnlyCollection<T>, arrays or ImmutableArray<T> (where empty means zero items). Null references or default ImmutableArray<T> instances are accepted and do not throw an exception.
