title: In Autofac how do I change the instance that is registered after Build has been called?
body: <p>So lets say i have this code</p>
  
  <pre><code>var builder = new ContainerBuilder();
  builder.RegisterInstance(new MyType());
  var container = builder.Build();
  </code></pre>
  
  <p>Then some time later I want to change the instance of <code>MyType</code> for all future resolves that are called on <code>container</code>.</p>
