  I have tried <code>Enterprise Architect</code> but that software is unable to detect <code>C# 6</code> syntax. For example whenever there's <code>public static String readonlyText =&gt; "123";</code>, it skips the class. </p>
  
  <p>What's the solution to generate class diagram based on ASP.Net Core code?</p>
