We really need the extension mappings to work again asap. Stuff like that can't be 'broken' all of a sudden between releases.
And we really like to use the Nuget packages because those are more milestone-like deliveries. Or at least, so it seemed.
I know using the bits is at my own risk and we aren't using it for customers, but our test department needs releases of our beta product and in a sense, they are customers to.
I am referring to earlier questions I posted where 'AddQueryStringMapping' works fine but 'AddUriPathExtensionMapping' does nothing.
