I am using Visual Studio 2012 (in x64 bit mode that is).

Binary D distribution also comes with phobos64.lib that C++ 
executable has to link. With VisualD plugin you can just add D 
static library project to the solution and the link C++ exe to 
it. It is very easy to make back-and-forth function calls between 
C++/D. I recommend Adam Ruppe's excellent "D Cookbook" 
Integration chapter on the details on how to expose this for 
cross-lang usage.

It does not all work correctly tho. I reported my issues on 
"learn" subforum but didn't get much help. In short: it seems not 
everything in D run-time (Phobos) gets properly initialized even 
after successful rt_init() call. In my case simple call to 
writeln() causes a crash because stdout is not properly 
initialized on D'd side.

Happy hybridizing!
