This doesn't compile, because Render is an instance method - you were
calling it by using the class name: 'PageBase'.

If this did even compile and run - you would get a stackoverflowexception -
because you would constantly be calling the same method - the one you are
in!.

You want to call MyBase.Render(writer) - 'MyBase' is the keyword to refer to
the base class in VB.
