In the past (a couple of years ago), I searched for a decompiler, so that I can recompile an assembly that I no longer have the source code. I found Anakrino by Saurik.
This software was good in the time, but I didn't found any updates since 5 years of that software. So, I began to search for a new one, and I found a very stable version that seems to be build from the same source (maybe I'm wrong) this one is from Lutz Roeder, and is named Reflector. It is a very stable and recent version, of course, available for FREE.

I received an email from Andre Seibel. He said that:
Reflector is NOT based on Anakrino. Reflector in fact existed long before Anakrino and is written in C#. Anakrino seems to be in Managed C++ and hasn't gone very far.
He doesn't seems to be the author, but it's reflection is logic. Maybe the author of he reflector can tell me the thruth?
