ObservableObjectBaseGetT(T, String) Method

Gets the value of a property or defaultValue if no value is stored for it. No new value will be stored if the property does not exist. If the default initial value is too complex and should not be evaluated every time when the property is get, or to throw an exception for an uninitialized property use the other Get overload.
For an example, see the Remarks section of the ObservableObjectBase class.
