Please see the answer about obfuscation. You should understand that obfuscation does not prevent reverse engineering, it just makes it harder to understand what the code is doing. There are much more delicate and powerful products used to prevent reverse engineering, but nothing can fully guarantee such protection. All products are saw so far were proprietary and expensive. Are you sure you want to go for it? Are you sure your code is so valuable that anyone would like to reverse-engineer it?

Yes. Any thing is breakable provided time and resources. So rather than wasting money on obfuscation, we can think of coding the core logic in C++ libs and then wrap them in a C++/CLI dll for consumption in C#. In this way you can secure your core at least

Solution 1

Its called Obfuscation[^]. There are plenty of answers for this kind of question already. See the following

csharp Obfuscate[^]
.net code obfuscation[^]

You can also refer to these URLs from CodeProject[^] or Google[^] if you don't find the 2 solutions enough.

Solution 2

All .Net assemblies need obfuscation so that others cannot figure out your code. Take a look at Crypto Obfuscator .
