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

Bear in mind that 99%+ of your users aren't going to be interested in examining your executable to see how it works.

Given that so few people are even going to bother trying and that most obfuscators can be worked around, is it worth your time and effort?

You'd be better off investing the time into improving your product so that more people want to use it.
