title: Locating all comments within a code file using the Visual Studio 2017 SDK
body: <p>Specifically, I want to obtain a list/collection of all the code comment lines for use in a small extension to intellisense to handle certain varieties of markup done through comments in C# and C++. </p>
  
  <p>I strongly suspect Visual Studio already maintains such a list without me needing to explicitly query a language parser for the information directly, but if it exists, I have no idea where to look for it. </p>
