title: Data-Level Authorization (ASP.NET Core 2.2)
body: <p>How can I use claim for data-level authorization?  </p>
  
  <p>For example, </p>
  
  <ul>
  <li>Project 1: User A, User B, User C</li>
  <li>Project 2: User B</li>
  <li>Project 3: User C</li>
  </ul>
  
  <p>Meaning</p>
  
  <ul>
  <li><p>User A can only access Project 1</p></li>
  <li><p>User B can access both Project 1 and 2</p></li>
  <li><p>User C can access both Project 1 and 3</p></li>
  </ul>
  
  <p>How do I implement the above logic?</p>
