SILVERLIGHT IS Not SAFE (privacy)

We developed project with silverlight + wcf. We all scared about the xap file decompilers. May be code and function are not safe using silverlight.

I am prepared application using SL4 + WCF. Then i try to find some sample in silverlight application. i got some crazy software here screen snap below

Silverlight Spy is an deployment application of XAP.

here we download all dll and service config files. Now we have a service url then using WCF Test Client Application access service function !

DLL's: Decompiler开发者_StackOverflow社区 of DLL's already available!!

Here i wanna know how to make secure code using silverlight ?

Decompilers work for all the applications targeting .net framework and not just silverlight. If you want to hide the implementation of code, there are several free and commerical obfuscators in the market for that purpose.
