VS Community Edition now includes the formerly Enterprise c++ coverage tool, so I can easily pull out local coverage metrics from debug builds (unoptimized builds don't miss lines). Formerly we had only Linux coverage (in CI), so this gives a more complete picture, due to some conditional compilation. Also makes it fast/easy for me to see where the gaps are. Our CI bar has long been set to 80%, which is the level where unit testing provides a material code quality benefit. Getting the last 20% is a lot more work, because you always get the easy stuff first (which is also why it's not worth as much). We'll get to 80%+ on all repos to hit the release gate, and on network/server protocols much of that will be hit by functional tests. And I'll keep working toward that 100%.
