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

But is it really worth the effort to select, buy and use such a tool?

I found Eazfuscator cheap (free), and easy to use: took about a day. I already had extensive automated tests (good coverage), so I reckon I could find any bugs that are/were introduced by obfuscation.
