.di files don't need to be passed to the compiler. They are 
neither compiled nor linked. The whole point of them is that they 
only provide the declarations, not the implementations. You still 
need to link to a compiled implementation, either in the form of 
an object or library file.

I've never used Visual D (or DMD for that matter) to create a 
DLL, but I assume an import library should have been produced 
along with the DLL. Are you linking to it in your executable 
project?
