Self-modifying C# (MSIL) code?

Question

How can I dynamically modify MSIL code in-memory with C#/.NET?

And yes, I'm really looking to replace existing code that's already in memory on the fly.
Specifically, I'm not:

Looking to only generate new code (via expression templates, ILGenerator, etc.)
Trying to emit a new binary module in the hopes of loading it into memory later

As far as I am aware, this is not supported in .net IL. Why is this specific scenario required? — flacnut, Jul 01 '13 at 23:26
@newStackExchangeInstance: I can't really discuss the project I'm working on, all I can say is that having this capability would help a lot. — user541686, Jul 01 '13 at 23:51
@sheldo Given that Mehrdad is talking about a Virtual Machine Runtime, whose premise of an easily modifiable IL comes with the .NET territory, it is definitely possible. Additionally with `unsafe` and/or Marshalled invocations there is little one can not do. — Lorenz Lo Sauer, Sep 27 '13 at 08:11

It seems to require native code... is there no way to do it from managed code? – user541686 Jul 02 '13 at 03:12
