Hi All,

I am developing the desktop application in C# windows. I want to protect the dll from reverse engineering so that no one can see my code.

How can i protect the code? Is there any code or way to protect the dll?

Please help me to solve this problem.

Thanks in advance

From the tools menu select Dotfuscator
That will rename variables, methods, classes...

Hi Jatin Nahar,

I hope the "Crypto Obfuscator For .Net" is the one which will help you to protect the DDL from the decompilers.

Since this is not a freeware, but gives you the more protection to your DDL from a decompiler.

Just give a try this by downloading Crypto Obfuscator For .Net Free Trial...

Which version of VS do you have, it might not be available in the free versions.

have a look at:

ps.  I think it isn't included with the express versions because you can only use it for personal use, not for commercial use (so why do you need to obfuscate any code)
