title: How can I serialize a Lookup
body: <p>I'm working on a project for work where I need to binary serialize every object returned by one of our <code>ProxyFactories</code>.
  We decided it would be fine to require a <code>Serializable</code> attribute on every class to be returned but my problem now is that I can't serialize the <code>LookUp</code> object that <em>.NET</em> provides.</p>
  
  <p>Is there anyway that I can work around this without changing this to be a <code>Dictionary</code>?</p>
  
  <p>My only other idea is to create my own class to implement ILookup but surely there must be an easier way.</p>
