Various 7.1 Clean-up Fixes (#4251)

## Fixes #4210 and Fixes #4158

Cleans up sample for #4248 (though underlying issue remains to be figured out later).

Fixes a sample and cleans-up a few items we missed in our nuget packages. Just need to validate output from CI, but should be fairly straight-forward.
