Properties

	Name	Description
	Dispatcher	Dispatcher associated with this object. (Inherited from NotifyPropertyChangedDispatcherObject.)
	MessageBoxService	(Inherited from ViewModelBase.)
	ParentViewModel	(Inherited from ViewModelBase.)
	UIHostService	(Inherited from ViewModelBase.)

Methods

	Name	Description
	AddDependencySource(String, INotifyCollectionChanged)	(Inherited from NotifyPropertyChangedDispatcherObject.)
	AddDependencySource(String, INotifyPropertyChanged)	(Inherited from NotifyPropertyChangedDispatcherObject.)
	CheckAccessBeginExecute	Executes the specified action on a thread associated with object's dispatcher. This invokes a BeginInvoke on the Dispatcher, does not wait for the action to complete -- returns immediately. (Inherited from NotifyPropertyChangedDispatcherObject.)
	CheckAccessExecute(Action)	Executes the specified action on a thread associated with object's dispatcher. (Inherited from NotifyPropertyChangedDispatcherObject.)
	CheckAccessExecute<TResult>(Func<TResult>)	(Inherited from NotifyPropertyChangedDispatcherObject.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetDependencySourceName(INotifyCollectionChanged)	(Inherited from NotifyPropertyChangedDispatcherObject.)
	GetDependencySourceName(INotifyPropertyChanged)	(Inherited from NotifyPropertyChangedDispatcherObject.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetWaitCursor	(Inherited from ViewModelBase.)
	HasErrors	Checks if at least one validation rule is broken.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	RaisePropertyChanged	(Inherited from ViewModelBase.)
	ReceiveWeakEvent	(Inherited from NotifyPropertyChangedDispatcherObject.)
	RegisterService	(Inherited from ViewModelBase.)
	RegisterServices	(Inherited from ViewModelBase.)
	RemoveDependencySource(String, INotifyCollectionChanged)	(Inherited from NotifyPropertyChangedDispatcherObject.)
	RemoveDependencySource(String, INotifyPropertyChanged)	(Inherited from NotifyPropertyChangedDispatcherObject.)
	ResolveService<TService>	Resolves the service. (Inherited from ViewModelBase.)
	SetAndRaisePropertyChanged(Boolean%, Boolean, String)	A helper method that sets property value and raises PropertyChanged event if the value has changed. Optimized implementation for System.Boolean type. (Inherited from NotifyPropertyChangedDispatcherObject.)
	SetAndRaisePropertyChanged(Int32%, Int32, String)	A helper method that sets property value and raises PropertyChanged event if the value has changed. Optimized implementation for System.Int32 type. (Inherited from NotifyPropertyChangedDispatcherObject.)
	SetAndRaisePropertyChanged(String%, String, String)	A helper method that sets property value and raises PropertyChanged event if the value has changed. Optimized implementation for string type. (Inherited from NotifyPropertyChangedDispatcherObject.)
	SetAndRaisePropertyChanged<T>(T%, T, String)	A helper method that sets property value and raises PropertyChanged event if the value has changed. (Inherited from NotifyPropertyChangedDispatcherObject.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	TryResolveService(Type)	(Inherited from ViewModelBase.)
	TryResolveService<TService>()	(Inherited from ViewModelBase.)
	UnRegisterService	(Inherited from ViewModelBase.)
	UnRegisterServices	(Inherited from ViewModelBase.)
	VerifyAccess	Enforces that the calling thread has access to this object. (Inherited from NotifyPropertyChangedDispatcherObject.)

Events

	Name	Description
	PropertyChanged	Occurs when a property value changes. (Inherited from NotifyPropertyChangedDispatcherObject.)

Explicit Interface Implementations

	Name	Description
	IDataErrorInfo.Error	Gets an error message indicating what is wrong with this object.
	IDataErrorInfo.Item	Gets the error message for the property that has the given name.
	IWeakEventListener.ReceiveWeakEvent	(Inherited from NotifyPropertyChangedDispatcherObject.)
