Protected Function SetPropertyNotifyAsync (ByRef field As IntPtr, newValue As IntPtr, ByRef notificationTask As Task, Optional cancellationToken As CancellationToken = Nothing, Optional propertyName As String = "") As Boolean

Parameters

field: IntPtr
nativeint

The storage location for the field behind the property.

newValue: IntPtr
nativeint

The new value to store in the field.

notificationTask: Task

If the property hasn't changed, this will be null. If the property has changed, this will be a task that will complete once the PropertyChanged event has been raised.

cancellationToken: CancellationToken

The cancellation token.

propertyName: String

The name of the property that is changing.

Returns

Boolean

true if the property value changed, false if it did not change.
