Need to address warnings in v1.x branch

[mathewc]

The build currently produces 68 warnings. We used to build clean, making it easy to spot the introduction of issues in a set of changes. All this noise makes people tune out.

We need to get the build clean again before we release.

Here are the current warnings:

@fabiocav Any chance this is resolved by your NET 4.7 changes?

[paulbatum]

@fabiocav any idea on what we can do here? Can our friends in .NET land help?
