Doesn't that though require TryDequeue to return some marker interface with a Message implementation and some "nothing" implementation? Sure, it's more elegant at the call-site, but you're stuck implementing 3 implementations in the actual code, which itself may be impossible if Message is an existing type.

@Telastyn: It also works if it just returns null. You could also use an Option type.
