Great work @jameshkramer

I had a couple comments to consider, along with a question for Maira

[BillWagner]

I realize this is expanding scope, but is this a good time to remove the private fields and change the later properties to auto-implemented properties?

@mairaw

[jameshkramer]

I don't think this is my call. It certainly is beyond scope, because it is well beyond the attitude of "get the articles merged and go from there". That does necessarily argue against it - we have already gone beyond scope, I think, which is not necessarily bad.

I might or might not be the right person to make such changes. I don't really understand what you propose, but if it only requires knowledge of C# I would be fine. If it depends on knowing LINQ, I might not be the best person.

[mairaw]

Let's keep the task focused on bringing the articles over. And then you can make the improvements later @BillWagner?

[mairaw]

@jameshkramer please resolve the new merge conflicts

LGTM. Left a few comments to be addressed before merging.
