GetHashCode	Serves as the default hash function. (Inherited from Object)
GetType	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
SetWithNotifyT	This is used to raise the PropertyChanging and PropertyChanged events if the new value does not equal the current property's value
ToString	Returns a string that represents the current object. (Inherited from Object)

Events

PropertyChanged	Occurs when a property value changes.
