ServicePointManager.ServerCertificateValidationCallback RRS feed

  • Question

  • How can I automaticaly accept a SSL certificate in WinRT has I was doing in .NET ?

     static ClientProxyHelper()
         ServicePointManager.ServerCertificateValidationCallback += AcceptAnyCertificate;
     private static bool AcceptAnyCertificate(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors error)
         return true;


    Thank you.

  • Hi Aleks,

    You cannot do this in WinRt.  There is no ServicePointManager exposed and no way to do your own certificate validation.  Your server cert will need to be valid and verifiable.

  • Hummm ... bad news.

    This is a development environment scenario that you should enable. No ?


    Moreover, I'm disappointed to see that, contrary to what we were told during the Build, the client part of WCF is not totaly the same.

    There is some minor differences (method or property renamed witch is very frustrating when you port an existing code) and some bigger (less binding, some classes disapeared, etc.)

  • Hi Aleks,

    Could you please tell me which APIs in WCF did you find missing which you would find useful to be added? Thanks.

  • Hi PiyushJo,


    I don't have a list of features that is missing in my pocket.

    For now, what is really blocking is not having the possibility to accept an auto-sign certificate. In a developpment environment, I think that almost all company use this type of certificate.

  • You can use fiddler web debugger to bypass the SSL issues.

  • Hi Aleks, you can unblock yourself by installing the server certificate in the client certificate trusted store.

  • Hi Aleks,

       I am creating a Win 8 Apps which access the WCF service to retrieve the data. I am also facing the same Issue with the SSL Certificate as your facing in the AcceptAnyCertificate. Any solution for this SSL certificate issue.

  • No Sorry Nazeer I didn't find any solutions.

  • Facing the same issue... And currently a no-go in one of projects I was planning to build. I'm writing a client app and protocol implementation requires SSL but not a valid certificate (allowing any user to setup a server easily without extra costs). I need to support any server. Requiring a valid certificate from hosts will at this point make my client application pointless.

    I'm a little bit disappointed at this time :(

  • Jeff,

    It's been a year and still no thing from MS about supporting self-signed certificates? First WinRt don't support WS-* so we have to use BasicHttpBinding, then on Basic, you don't allow us to test on self-signed cert so we can't test on our development environment.

    Is this platform just for game, reading news and not for business apps?

    For guys that don't know, you can use Fiddler to bypass the problem (per Yue Zhang)
