Methods

	Name	Description
	DetachEventSource	Detaches the event source.
	DetachEventSources	Detaches all event sources.
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Overrides ObjectFinalize.)
	GetDataErrors	Gets the validation errors for a specified property or for the entire entity.
	OnDataErrorsEvaluated	Called when data errors have been evaluated. Used e.g. to track data errors for each property.
	OnErrorsChanged	Raises the ErrorsChanged event.
	OnPropertyChanged(String)	Raises the PropertyChanged event for the property with the specified name. [NotifyPropertyChangedInvocator]
	OnPropertyChangedT(ExpressionFuncT)	Raises the PropertyChanged event for the property identified by the specified property expression. [NotifyPropertyChangedInvocator]
	RelayEventsOf(INotifyPropertyChanged)	Relays the property changed events of the source object. The properties to relay must be declared with the RelayedEventAttribute.
	RelayEventsOf(INotifyPropertyChanged, INotifyPropertyChanged)	Relays the property changed events of the source object (if not null) and detaches the old source (if not null).
	SetPropertyT(T, T, ExpressionFuncT)	Sets the property and raises the PropertyChanged event for the property identified by the specified property expression. [NotifyPropertyChangedInvocator]
	SetPropertyT(T, T, String)	Sets the property and raises the PropertyChanged event for the property identified by the specified property expression. [NotifyPropertyChangedInvocator]
	SetPropertyT(T, T, ExpressionFuncT, ActionT, T)	Sets the property and raises the PropertyChanged event for the property identified by the specified property expression. [NotifyPropertyChangedInvocator]
	SetPropertyT(T, T, String, ActionT, T)	Sets the property and raises the PropertyChanged event for the property identified by the specified property expression. [NotifyPropertyChangedInvocator]
	SetPropertyT(T, T, ActionT, T, String)	Sets the property and raises the PropertyChanged event for the property identified by the specified property expression. [NotifyPropertyChangedInvocator]

Extension Methods

	Name	Description
	SafeCastT	Performs a cast from object to T, avoiding possible null violations if T is a value type. (Defined by ObjectExtensions.)

Remarks

Also implements IDataErrorInfo and INotifyDataErrorInfo to support validation. The default implementation examines ValidationAttribute on the affected properties to retrieve error information.
