Activities of "zedvance"

I enabled the google and facebook authentication and the google works fine, but the facebook throws an intenral server error. Further investigation shows that no email is returned, even though the permission is granted.

Searching on stackoverflow recommends workaround and installing Facebook SDK (<a class="postlink" href="http://stackoverflow.com/questions/20928939/how-to-get-facebook-first-and-last-name-values-using-asp-net-mvc-5-and-owin?lq=1">http://stackoverflow.com/questions/2092 ... -owin?lq=1</a>) Is there an alternative or recommended solution/workaround for ASPNET Zero
