How do you post to a friend's wall using the C# Facebook SDK?

Question

So I tried to post on my friends wall using the following code:

var fb = new FacebookClient(_accessToken);
dynamic parameters = new ExpandoObject();
parameters.message = "Google is your friend";
parameters.link = "http://gidf.de/";
parameters.Name = "Test";
parameters.from = new { id = "100000", name = "me" };
parameters.to = new { id = "1000001", name = "friend" };
dynamic result = fb.Post("1000001/feed", parameters);

However, I get told that my application does not support this. I did some googling work, and read that [USER_ID]/feed is deprecated and that I have to invoke the feed dialog to ask the user to publish it. How would I go on doing this with the C# SDK?

As of February 6, 2013, you can't post to Friends Timeline on behalf of the user. Read Here: https://developers.facebook.com/roadmap/completed-changes/

Client-Side you can use the FB.ui method to pop up the feed dialog.
Here's an example: https://stackoverflow.com/a/15426243/1405120

Server-Side, you can use the URL Redirection.
