title: JwtSecurityTokenHandler.set_CertificateValidator method not found
body: <p>Just updated many of the packages for an Azure Mobile Service and now I get a "method not found" error. This does not seem to be a problem reported elsewhere yet. Any idea which package needs to be down-graded? Or another work-around?</p>
