This project is a VS extension that computes code complexity as-you-type.
The extension is supported by Visual Studio versions 2012 - 2019.
The complexity being computed is Simple Complexity, as introduced in the Code-Complete book. The computed complexity reflects how many decision points are in a given function, and the numbers should encourage developers to refactor over-complicated functions.
The extension is listed in VS Gallery: http://bit.ly/2LAADFY
