Solve the problem by any of:
* Implement INotifyPropertyChanged for DependencyObjectType or use a type that does.
* Implement INotifyPropertyChanged for Dispatcher or use a type that does.
* Use a type that implements INotifyPropertyChanged instead of Thread.
* Use a type that implements INotifyPropertyChanged instead of ExecutionContext.
* Implement INotifyPropertyChanged for DispatcherHooks or use a type that does.
* Make ObservableBatchCollection<PositiveViewModel> immutable or use an immutable type.
* Make PositiveViewModel immutable or use an immutable type.
* Make ObservableBatchCollection<RectangleViewModel> immutable or use an immutable type.
* Make RectangleViewModel immutable or use an immutable type.
* Make BitmapSource immutable or use an immutable type.
* Make DependencyObjectType immutable or use an immutable type.
* Make Dispatcher immutable or use an immutable type.
* Use an immutable type instead of Thread.
* Use an immutable type instead of ExecutionContext.
* Make DispatcherHooks immutable or use an immutable type.
- For immutable types the following must hold:
- Must be a sealed class or a struct.
- All fields and properties must be readonly.
- All field and property types must be immutable.
- All indexers must be readonly.
- Event fields are ignored.
* Use PropertiesSettings and specify how change tracking is performed:
- ReferenceHandling.Structural means that a the entire graph is tracked.
- ReferenceHandling.References means that only the root level changes are tracked.
- Exclude a combination of the following:
- The property PositivesDirectory.Images.
- The property PositiveViewModel.Rectangles.
- The property RectangleViewModel.BitmapSource.
- The property DependencyObject.DependencyObjectType.
- The property DispatcherObject.Dispatcher.
- The property Dispatcher.Thread.
- The property Thread.ExecutionContext.
- The property Dispatcher.Hooks.
- The type ObservableBatchCollection<PositiveViewModel>.
- The type PositiveViewModel.
- The type ObservableBatchCollection<RectangleViewModel>.
- The type RectangleViewModel.
- The type BitmapSource.
- The type DependencyObjectType.
- The type Dispatcher.
- The type Thread.
- The type ExecutionContext.
- The type DispatcherHooks.
