Roslyn based Diagnostics and CodeFixes enable you to provide ever-present guidance to junior developers. Are there coding practices you encounter that you wish the inexperienced members of your team outgrew? Don't complain. Write a Diagnostic and Code Fix using Roslyn to encourage your teammates to follow the advice you give them in person. In this session, you'll learn how to create extensions to visual studio that analyze code and report on poor practices. Even better, you'll learn how to implement code fixes that correct those poor practices immediately. After this session, you can help your inexperienced developers improve practices whenever they code. It will be like you're standing over their shoulder suggesting better coding style as they.
