title: sonarqube reporting private static methods as unused for c#
body: <p>I am getting sonarqube issue as <a href="https://i.stack.imgur.com/wQVgs.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/wQVgs.png" alt="enter image description here"></a></p>
  
  <p>It is reporting all private static members as unused. Is it a false posetive from sonarqube or I am missing something here?</p>
