title: Is a property "FullName" bad, when there are "FirstName" and "LastName"?
body: <p>I have an <code>Employee</code> class:</p>
  
  <pre><code>class Employee
  {
      string FirstName { get; set; }
      string LastName { get; set; }
  }
  </code></pre>
  
  <p>Sometimes I want to get the full name and it's tedious to write <code>emp.FirstName + emp.LastName</code> again and again and again.</p>
  
  <p>Is it bad practice to add a <code>FullName</code> property (because it's the same data twice or something)?</p>
  
  <pre><code>class Employee
  {
      string FirstName { get; set; }
      string LastName { get; set; }
      string FullName =&gt; $"{FirstName} {LastName}";
      }
  }
  </code></pre>
