Breaking change

WithCollectionProperty accepting ICollection as the expression property for the model are now obsolete. If your collection property does not fit any of the other overloads (it is not a List<T>, HashSet<T> or Collection<T>), ensure that the property is already initialized and use the method WithInitializedCollectionProperty instead.

Other changes

• The WithCollectionProperty methods now ensure that the collection property is of the exact same type of the expected collection. So if you're using the WithCollectionProperty overload that expects a collection property of Collection<T>, your model must have its collection property as a Collection<T>. If the property is of type ObservableCollection<T>, for example, which inherits from Collection<T>, an error will be thrown at runtime. For such cases, the WithInitializedCollectionProperty must be used instead.

• WithCollectionProperty overloads were added to support ICollection properties. These properties must be already initialized in the model, otherwise, an exception will be thrown.
• Existing WithCollectionProperty methods were changed, now if the collection property is already initialized, the extraction process will only add new instances of extracted data to it rather than always creating a new instance of the collection property.
