Protect .NET code from reverse engineering?

Question

Obfuscation is one way, but it can\'t protect from breaking the piracy protection security of the application. How do I make sure that the application is not tampered with,

Answer 1

Is it really worth it? Every protection mechanism can be broken with sufficient determination. Consider your market, price of the product, amount of customers, etc.

If you want something more reliable then go down the path of hardware keys, but that's rather troublesome (for the user) and more expensive. Software solutions would be probably a waste of time and resources, and the only thing they would give you is the false sense of 'security'.

Few more ideas (none is perfect, as there is no perfect one).

• AntiDuplicate
• Change the language, use the nice tricks that the authors of Skype used
• License server

And don't waste too much time on it, because the crackers have a lot of experience with the typical techniques and are few steps ahead of you. Unless you want to use a lot of resources, probably change the programming language (do it the Skype way).
