how to increase performance of silverlight 4 by reducing xap size by using assembly caching?

Hi ther,

I have created a silverlight 4 application. Its working fine in my environment. when i deploy in server & access that application from client, it gets loading for about 40 seconds since xap size is 440KB. On surfing the net, i came to know that by creating gextmap.xml files of third party dll's would created as zip files in client bin of silverlight web project.

Its for sure that system 3rd party dll's like Theming, etc gets converted. If i use 3rd party dll other than system dll's like coolmenu, etc., it is not converting as zip file. Rather it resides in xap size file itself.

So how can i make tat coolmenu.dll to be reside in web part of silverlight?

Thanks in advance.. Any Help., well appreciated..

Nas..
