Getting DUB to work with VS 2017

[Enjoys Math via Digitalmars-d-learn]

I did `dub generate visuald project_name`.

VS 2017 loads the .sln file except for red 'x's on the dub.json 
files.

My dub.json file looks like (if it matters):

{
        "name": "pegparser",
        "targetName": "PEGparser",
        "authors": [
                "Fruitful Approach"
        ],
        "description": "A parser for LED UX Designer using pegged.",
        "copyright": "Copyright 2017, fruitfulappro...@gmail.co",
        "license": "proprietary",
        "dependencies": {
                "pegged": "~>0.4.2",
                "pyd": "~>0.9.9",
        }
}

Building gives errors although doing `dub build` at the command 
line works.

Shouldn't the build command be `dub build` instead of `$(CC) -c` ?

How do I make this work.  Otherwise, I will just make calls to a 
D app from python over the command line or something...
