Call D code from C#

[anthony]

Hi to all here,

(another one here that wants to desperately use D in his work 
environment!)

So, I am a C# and C++ guy who is used to high quality tools and 
UI libraries. I discovered VisualD and I settled on using it, it 
is really awesome!

The only problem that concerns me is the lack of a UI library to 
use with the language. GTK+ is not an option for me. Qt is but I 
do not see any way to use it from D.

I am thinking about using D for the business logic of my programs 
(let's say on Windows, for start) and then C# for the UI stuff.

Is there a way to access D code from C# ? Some path I need to 
follow, some hint... ?

Thanks a lot for any help !
