No it's not. Reading CIL code in the Reflector is often better than reading it in Visual Studio: the Reflector is an amazing little tool with one of the best integrated cross-referencers I've used.

I'm guessing you've never actually used it, because you're using the word "disassemble" to describe it. Like JVM bytecode, CIL is unambiguous, explicitly typed, and doesn't rely on aliasing; therefore, like JVM bytecode, it is easily reversed back out to a high level language. You're not reading CIL opcodes in the Reflector, you're reading C#.

I wonder if this is a valuable lesson for developers here. Bytecode VMs do not offer strong protection of your source code.
