Why doesn't email gets returned from Facebook.Rest.Api.Users.GetInfo()?

I'm using 开发者_开发问答.NET MVC 3 and I'm trying to get users email from Facebook connect. I have searched around and feels like I have tried everything, but apparently I'm doing something wrong.

This is my loginbutton where I set email permission

<fb:login-button perms="email, offline_access" autologoutlink="false" />

And this is my server-side call for getting user information

var user = Api.Users.GetInfo(GetUserID());

In debug mode I can see that user is set and authenticated, but email is not set, even though I've set "email" as a permission and after user has granted. Please, does anyone know what I'm doing wrong?

TIA

Bump

It's been three days and still no response. I was thinking, do I have to registrate user to get access for email? Seems kinda odd if that's the case, since user grant email permission. Any kind of though is appreciated. Thanks!

I installed (Web.Helpers) Facebook.Helpers, and it worked like a charm. Even though I've followed fackbooks guidlines, I must have done something wrong. Still weird that I got the user informationen, but not the email.
