Alternative for Obfuscation in the .NET world

Just a few minutes ago, I read that there are a number of tools, many free, that allow you to convert a C# .exe back to a VB solution. This means that my proprietary code can be viewed, edited, and recompiled/redistributed. Is there a way to prevent this?

In short you need to use Obfuscation. To name a few.

  1. Dotfuscator
  2. Obfuscator
  3. Skater (Freeware)
  4. DeployLX CodeVeil
  5. Plus Visual Studio comes with a light version of Dotfuscator.

You can read this MSDN article that has advice on how to obfuscate your code.
