VS Demonstration Project

I've attached a project that demonstrates different behavior when run on the Mono libraries compared to the Microsoft libraries.

The program calls TryGetValues("Location",out headerValues) on the content header of an HttpResponseMessage. In Mono TryGetValues() then calls CheckName() to validate the "Location" header field and throws an exception. I understand that the proper use of the "Location" header field is in an http response header (not in a content header as demonstrated) and I think that is why it fails the CheckName() validation.

My understanding is that by Microsoft convention members using a "Try" pattern ought not to throw exceptions. And indeed when compiled against the Microsoft libraries no exception is thrown.
