ahem Actually, I wrote the first .NET decompiler: Exemplar, with a GUI later called Anakrino; it was even quite popular. Microsoft actually used it as a test case for their compiler occasionally. ;P Reflector existed at the time, but it was not a decompiler: it was just a class browser and disassembler. He added the decompilation features due to pressure from Anakrino, to which I was adding class browser functionality (and was orders of magnitudes faster, as I hated waiting around for Reflector to analyze the binary, which used to take forever). (Incidentally, Anakrino was open source.)
