I used Windows.Security.Authentication.Web.WebAuthenticationBroker.AuthenticateAsync to perform Facebook authentication and it always works well. Refer to article https://docs.microsoft.com/en-us/uwp/api/windows.security.authentication.web.webauthenticationbroker However, it didn't work and throws error message "value does not fall within the expected range." recently. I verified the call back URL from " WebAuthenticationBroker.GetCurrentApplicationCallbackUri().AbsoluteUri" and found out that the Windows App Id is changed! So I updated the related Windows App Id in the Facebook App setting's configuration page, and now the authentication works again!
