JwtSecurityTokenHandler.set_CertificateValidator method not found

Question

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?

[MissingMethodException: Method not found: 'Void System.IdentityModel.Tokens.JwtSecurityTokenHandler.set_CertificateValidator(System.IdentityModel.Selectors.X509CertificateValidator)'.]

Answer 1

Ive just had the same issue and have got the Mobile Service working again by

In Package Manager Console in VS

uninstall-package WindowsAzure.MobileServices.Backend.Entity

uninstall-package WindowsAzure.MobileServices.Backend.Tables

uninstall-package WindowsAzure.MobileServices.Backend

then

install-package WindowsAzure.MobileServices.Backend -Version 1.0.342

install-package WindowsAzure.MobileServices.Backend.Tables -Version 1.0.342

install-package WindowsAzure.MobileServices.Backend.Entity -Version 1.0.342

Not sure why this is happening though
