I am using MVC 5 with OWIN identity authentication.
I have not touched the default auth code. (VS 2013).
Sometimes I get "error: Invalid token" when UserManager.ConfirmEmailAsync() is called.
I want to know if it's the case were a user clicked the confirm link in his inbox too late.
How can I get a more detailed exception telling me if the token has expired ? (or check it myself somehow)
