title: Find all unused code in my project (Rider/VSCode)
body: <h3>Goal</h3>
  <p>Ideally, our projects contain no unused <em>namespaces / methods / functions</em> and <em>classes</em>.</p>
  <p>It is fairly simple to find the number of usages of all of these, for instance;</p>
  <p><a href="https://i.stack.imgur.com/aSSJcm.png" rel="noreferrer"><img src="https://i.stack.imgur.com/aSSJcm.png" alt="enter image description here" /></a></p>
  <p>Has two usages while the following class is never used:</p>
  <p><a href="https://i.stack.imgur.com/Q1SPem.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Q1SPem.png" alt="enter image description here" /></a></p>
  <p>Such code can remain unnoticed for quite some time, while providing unwanted overhead to the total solution.
  What I'd like to achieve is an overview of all unused code, so developers can easily assess what should and shouldn't stay in the solution.</p>
  <h3>Question</h3>
  <p>Of course we're not going to manually search for these...
  How can we find <strong>all unused code</strong>?</p>
