Doesn't just Mono have an interpreter (which is now being added as part of tiered compilation)? Aside from .NET Micro. I was under the impression that .NET by and large was JIT-only. Yes, by now it's more complex, and there have been multiple different implementations, few of which would be relevant on a Windows Server environment for ASP.NET. But AFAIK a situation like in Java where the official implementation has an interpreter and a JIT (and debugging usually falls back to interpreting with horrible performance) has never been the case in .NET.
