title: Do I need to use await with both Add and SaveChanges?
body: <p>I have code like this now:</p>
  
  <pre><code>public async Task&lt;IActionResult&gt; Create(PageVM page)
  {
  ...
      await _context.AddAsync(dto);
      await _context.SaveChangesAsync();
  }
  </code></pre>
  
  <p>I am wondering if I should use <code>await</code> and <code>async</code> methods with both <code>Add</code> and <code>SaveChanges</code> or is using it just in one place enough?</p>
