    text
    copied!<p>Developing a WP7 app, and I'm trying to post something to the user's feed. We have all this working on iPhone already, and we have a test account created already. With the iPhone it's able to post to our test user's page.</p> <p>I'm trying to use the Facebook C# sdk to do the same thing, using the same account. I can successfully login to the test user's account and obtain the AccessToken. When I login, the extended permissions I request from the user are "read_stream", "publish_stream", "publish_checkins".</p> <p>When I try to do something like this:</p> <pre><code>var client = new FacebookClient(access_token); var parameters = new Dictionary&lt;string, object&gt; { { "message", "Howdy!" } }; client.PostAsync("/me/feed", parameters); </code></pre> <p>Then it fails, and observing client.PostCompleted I see the error is:</p> <blockquote> <p>(EntCannotSeeExistenceException) The entity (class EntPlatformTestUser) backed by id 1234 cannot be seen by the current viewer 1234 (EntID: 1234)</p> </blockquote> <p>I found a blog post[1] where someone was running into this exception, and he solved it by switching out of sandbox mode. But we're already not in sandbox mode. Plus, as I described above, everything is working just fine using the iPhone SDK. This leads me to think that I'm just doing something wrong with the C# SDK.</p> <p>[1]. <a href="http://test.ical.ly/2011/03/10/facebook-graphapi-uncaught-entcannotseeexistenceexception-the-entity-class-entapplication-backed-by-id-12345-cannot-be-seen-by-the-current-viewer-12345-entid-12345/" rel="nofollow">http://test.ical.ly/2011/03/10/facebook-graphapi-uncaught-entcannotseeexistenceexception-the-entity-class-entapplication-backed-by-id-12345-cannot-be-seen-by-the-current-viewer-12345-entid-12345/</a></p>
