Visual D adds a new task "CompileD" to msbuild together with a new "Item
Type" that gets automatically assigned to items with extension .d. This
task creates object files that are added to the linker command line in
addition to some additional options like library search paths.

You can just drag a .d file into any VC project to integrate it with
compilation and linkage. The D compiler options page will appear
automatically. (Depending on what your code does you might have to add
the phobos library to the linker settings, but it is supposed to be
automatic, too).
