After further experimentation it looks writing a WinDbg extension that will let one write WinDbg extensions in .NET is actually feasible. If you remember, I’ve talked about it in my previous post on the subject.

I could have gone the easy way and written some code in .NET exposed as a COM object and make my WinDbg extension call that managed code which will do all the rest, but that would be too easy and a lot less fun 🙂

Therefore, I’ve decide to gain some experience and knowledge in the .NET CLR hosting API.

I’m using the hosting API to bind and start the CLR, call the rest of my .NET code and pass the various interfaces that WinDbg is passing me back to the .NET code.

The challenge is to convert the interface definitions of the various WinDbg interface used to interact with WinDbg to .NET. It’s a bit of a tedious job, but someone has to do it… don’t you think?! 🙂

Anyhow, once I’ll finish the part about the CLR hosting APIs I’d write a long post about this subject and what I’ve learned while using this API so stay tuned!

Oh, one last thing. In that previous post tinkered with the idea of using some other way of instrumenting WinDbg instead of using its archaic and strange scripting language (actually that’s WinDbg’s command line interface turned into a scripting language).

Anyhow, technically I can enable any language, compile the script at runtime and run the assembly, but its a bit annoying. There is the ability of using IronPython or some other .NET dynamic language (maybe JScript .NET).

What do you think? would you like to be able to script WinDbg in your favorite .NET scripting language?
