I could be interested in building a Reflector clone if somebody would write an F# plug-in to the project. I would probably start with looking at the CCI-Metadata project on Codeplex, and the Microsoft Phoenix compiler framework. Mono has similar libraries, but I only know a very small subset of Mono.Cecil API.

I did look into cloning Reflector when Red Gate originally acquired it. The work involved looks similar to that needed to build a .NET compiler, but in reverse. That is, you take a low-level machine representation; then build up a control flow graph; then map that control flow graph onto common high-level constructs such as if statements and for loops.

I'm very familiar with engineering compilers and de-compilers. Have you seen Microsoft Phoenix? It lets you sink/hoist intermediate representations; the key for this would be having an API that allows ordering graph rewriting rules so that you can take the MSIL and convert it the right higher-level form (e.g., should this use LINQ? Well, what does the app settings say the user wants to see the code as?). Anyway, since Reflector is written in C#, it would be able to develop a clone much faster using code generation, since I bet Reflector uses a ton of Visitor patterns and needless C# boilerplate.

I won't promise performance comparable to Redgate's Reflector, but my rule of thumb is Correct. Clear. Fast. In that order.

I hadn't seen Phoenix before reading your comment, but I like the look of it. Looks useful for general compiler tinkering.

When I looked at this a while back, I was trying to do it in C# on Mono.Cecil. I got bogged down writing things like CSharpWhileLoopVisitor...

Reflector uses Mono's Cecil. It ships with a copy of the Cecil license.

Thank you very much for that tidbit.
