title: Returning Task<bool> from LINQ's Any method?
body: <p>I have this interface :</p>
  
  <pre><code>public interface ISign
  {
     Task&lt;bool&gt; IsRegisteredCopy();
  }
  </code></pre>
  
  <p>Implemented it:</p>
  
  <pre><code>public class Sign : ISign
      {
          TabibContext context = new TabibContext();
          public Task&lt;bool&gt; IsRegisteredCopy()
          {
              return context.Doctors.Any();
          }
      }
  </code></pre>
  
  <p>So I need to return Task from <code>Any</code> method which is not available!</p>
