Hi, thanks for posting!
NCrunch does have a console tool that can be used inside a CI system to capture and report code coverage information. See here for more details -
http://www.ncrunch.net/documentation/tools_console-tool.
Most of the work done on this tool is targeted towards Team City rather than VSTS, though assuming you're able to set up VSTS to run things on a command line and retrieve artifacts, you should be able to get it working.
The
setup guide for the tool describes a way to integrate with TFS using a special project structure. This was last tested a few years ago so I'm not sure if it still works. It may take a little tinkering to find the best solution for your environment.
