Should you obfuscate a commercial .Net application?

Question

I was thinking about obfuscating a commercial .Net application. But is it really worth the effort to select, buy and use such a tool? Are the obfuscated binaries really safe

Answer 1

It's quite simple to reverse engineer a .net app using .net reflector - since the app will generate VB, VC and C# code straight from the MSIL, and it's possible to pull out all kinds of useful gems.

Code obfuscators hide code quite well from most reverse engineering hacks, and would be a good idea to use on proprietary and competitive code that adds value to your app.

There's a pretty good article on obfuscation and it's workings here
