Question

I download the latest version and successfully tested the Mvc3Web sample.
I tried to extend it to get email and friends but the CanvasAuthorizer is failing.
The code below is not working:
CanvasAuthorizer _authorizer = new CanvasAuthorizer {Permissions = {“publish_stream,offline_access”};
throwing an exception complaining about appId being empty.
Any idea how to acheive this? It’s pitty that the samples are missing the permissions request functionalities.

Answer 1

change the code to use permissions as array.

CanvasAuthorizer _authorizer = new CanvasAuthorizer {Permissions = new[] {"publish_stream", "offline_access"}};

Update:
Also make sure to have proper app settings in web.config for the application.
or set it programatically (during application_beginrequest)

FacebookApplication.SetApplication(new DefaultFacebookApplication{ AppId = "...", AppSecret = "..." });
