Unfortunately they've broken the code coverage highlighting in dotCover in this release. Instead of highlighting the whole line the way it used to, there is now a tiny little sliver in the left gutter that you have to hover over to get the highlighting to show up.
When will Microsoft buy this company and integrate ReSharper into Visual Studio already? Having to make two payments (one for the IDE and the other for the plugin) instead of one is not very appealing.
Great release and VS2017 RC support to play with! Also, can't wait for Rider IDE. Hope it will include all the latest goodies!
