Remarks

To return an object retrieved by the specified key, the GetObjectByKey<ObjectType> method invokes the BaseObjectSpace.GetObjectByKey method, passing the required key as the key parameter. The value returned by the invoked method is cast to the type designated by the specified generic type parameter. Note that the invoked BaseObjectSpace.GetObjectByKey method does nothing and returns null (Nothing in VB). So, it should be overridden in the BaseObjectSpace class' descendants.
