title: How to create proxy if you have more than one interface using ClientBase<T>?
body: <p>I have a service hosted that have two interface A and B. I'm trying to implement proxy class for my client by using ClientBase. However, I don't know how to declare it.</p>
  
  <p>This is what I thought it should be:</p>
  
  <pre><code>public class ServiceProxy : ClientBase&lt;IA&gt;, ClientBase&lt;IB&gt;, IA, IB
  {
  .......
  }
  </code></pre>
  
  <p>Is that the right way to declare it ? If not, what would be the correct way ? Thank you.</p>
