Azure Mobile Service - Facebook logout
<p>I created .NET app with Azure Mobile Service Facebook Authentication. I used credential:</p>

<pre><code>// Login with the identity provider.
        user = await App.MobileService
            .LoginAsync(provider);

        // Create and store the user credentials.
        credential = new PasswordCredential(provider,
            user.UserId, user.MobileServiceAuthenticationToken);
        vault.Add(credential);
</code></pre>

<p>How do log off ?</p>
