title: C#: Use Task<> inside Tuple
body: <p>This would work if I remove <code>Tuple</code> and just using <code>Task&lt;bool&gt;</code> or <code>Task&lt;string&gt;</code>. </p>
  
  <pre><code> public async Tuple&lt;Task&lt;bool&gt;, string&gt; Test()
          {
  
              //....
  
              return new Tuple&lt;Task&lt;bool&gt;, string&gt;(false, "a string");
          }
  </code></pre>
  
  <p>Any idea how to make this work?</p>
