title: Ref in async Task
body: <p>How I can to pass a reference as a parameter to Async method in Windows Store App ? <br> I'm looking for something like this:</p>
  
  <pre><code>var a = DoThis(ref obj.value);
  
  public async Task DoThis(ref int value)
  {
      value = 10;
  }
  </code></pre>
  
  <p>But error:</p>
  
  <blockquote>
    <p>Async methods cannot have ref or out parameters</p>
  </blockquote>
  
  <p>Has any another way?</p>
  
  <p>Note:<br>I need to pass exactly obj.value. This method would be used by different types of objects, by same type of objects, by one object, but I will pass obj.val_1, obj.val_2 or obj.val_10. All values will be same type (for ex string)</p>
