Hello Crespo,

use obfuscators for this.
But could you describe why you consider that reversing your code could harm
u?
I hope your app is not a some kind of revolutional algorithms for video/audio
processing.
First of all, you can point in the licence that decompliling breaks the contract.
Second, do you really think that even smth look there it could understand
enough to harm you?

I recomend to read this http://www.yoda.arachsys.com/csharp/obfuscation.html
