I can't really follow what you've been doing, but that's maybe because I 
don't use C# very often. D follows the link model of C/C++:

- if you have code shared between different projects, put it into a 
project that builds to a static library

- an executable using the library needs a 'project dependency' to the 
library, but does not need to include/compile the files of the library 
itself. Visual D will automatically add the output file of the library 
project to the link command line for the executable

- you'll probably need to import files from the library, so you have to 
add the library source folder to the "additional imports" option

The last option could also be set automatically for existing project 
dependencies, that's something I wanted to add eventually.
