I am testing intellilock and .Net Reactor to protect the code of dlls and exe's created with Vs c# and i find that with dotpeek the code appears perfectly as i have written it and i have been trying with all the options. However, i have tried commercial applications and they seem protected.

What program should be used?

Solution 1

You might give SmartAssembly by Redgate a try: .NET Obfuscator, Error Reporting, DLL Merging | SmartAssembly[^]
Here are some other alternatives: Visual Studio Marketplace[^]

I have tried the program and the code appears obfuscated but it looks too much, like the internal structuring.

In contrast, with many other commercial programs, Dotpeek displays the message "Not Supported." They are using another program. Which one?

I frankly have no idea, maybe you can contact one of the manufacturers to get an answer to your question. Did you try Dotfuscator too ?

If you try JetBrain DotPeek with dlls of programs that you find on the internet, you will see that it shows the message "Not supported". It's what I want. What are you employing? DotOfuscator I have not used it.

We used SmartAssembly for a while, but now we use Dotfuscator as this allows us to mix C# and C++ projects. Dotfuscator is probably the most used obfuscator.

Anti-Reflector .NET Code Protection[^]

Protect Your Source Code from Decompiling or Reverse Engineering .NET Assemblies[^]
ConfuserEx[^]

A little Google goes a long way...

I have tried ConfuserEx with a dll and upon completion it shows the error that there is no .exe

I have tried with the entire .bin directory and at the end it shows another message. I dismiss this solution because it is not well finished.

[ERROR] An IO error occurred, check if all input / output locations are readable / writable.
Exception: System.IO.IOException: The operation could not be completed because the file contains a potentially unwanted virus or software.

in System.IO .__ Error.WinIOError (Int32 errorCode, String maybeFullPath)
