Visual Studio + Visual D helper stuff not working

[Jason Alexander via Digitalmars-d-ide]

I created a new D project and added some source code from a git 
package which just contained a lot of d files in various 
sub-dirs. I did this so I could view the code in with proper 
highlighting and useful searching features. I simply dragged the 
files into the solution and VS shows them. I can double click and 
view any file.

Unfortunately the code doesn't compile(the hello works main.d) as 
it says it can't find dmc. Not sure why it needs dmc...

Anyways, I don't care about compilation. I just want to use "find 
all references", "goto definition", etc... But they don't return 
any results... even if there are multiple references in the same 
file.

Any ideas why these search features won't work? Does the project 
have to be compiled?
