I am looking for a disassembler or better, a decompiler for .net. The situation is that the source code for an assembly written by one of my predecessors is lost and I'd like to take a look to see what it's doing.

I know that ildasm comes with the Visual Studio installation so I can get at the MSIL, but I was hoping there was a program clever enough to work back to the C# code (or best approximation).

Are there any tools for this out there?

(If not, I suppose it'll be a good excuse for me to sit down and start to learn MSIL)

Now that Red Gate have started charging for the .NET Reflector tool you might want to check out these free alternatives instead...
