How do I wrap MembershipUser
<p>How would i wrap MembershipUser so that the call below returns. Reason for wrapping is I would like the return result to be an interface to I can mock the user.</p>

<pre><code>public IMembershipUser GetUser(string username, bool userIsOnline)        
        {
            var user = Membership.GetUser(username, userIsOnline));

            //Do something 
            return WrappedUser;
        }
</code></pre>

<p>Thanks</p>
