Code Obfuscators

Although it's probably the case that the hobbyist developer needn't worry too much about his .NET CIL code being decompiled, there are some free assembly obfuscators that seem to work: OrangeHeap (~ 1.35 Mb download) and Confuser (~2.2 Mb download; available here). I prefer the latter.

Tools like these have a way of becoming vaporware. Nevertheless, at the time I write this, you can find OrangeHeap here on the internet, and Confuser here.
