Get types from NOT loaded assembly

[justJR]

I need to enumerate types in a certain namespace which physically lies in a Silverlight dll. But I have to do it on a server (asp.net app).I have xap file, I can read it with zip and get the dll I need.However I want not to load that assembly in memory (I think it might not get loaded as it is Silverlight app) also as long as I remember loaded assembly cannot be unloaded (dont want to junk server memory just to get few strings).Any ideas?
