The PrivateThreadingModel class describes a behavior of objects in which their threading model is determined by the parent they are assigned to in a parent-child relationship. Objects with this threading model are considered a private state of their parent object and cannot be accessed from a different object.
The ReaderWriterSynchronizedThreadingModel class describes a threading model where several threads can have concurrent read-only access, but where writing to the object requires exclusive access. To use the ReaderWriterSynchronizedThreadingModel, apply the ReaderWriterSynchronizedAttribute custom attribute to a class.
The ThreadUnsafeThreadingModel class describes a threading model an object cannot be accessed concurrently by several threads. In case of concurrent access, a ConcurrentAccessException exception will be thrown. The thread-unsafe threading model is not strictly a model, because it cannot be deterministically verified. To use the ThreadAffineThreadingModel, apply the ThreadUnsafeAttribute custom attribute to a class.
