title: How to make a Request in a masstransit WhenEnter block
body: <p>In a masstransit saga I can make a request like so:</p>
  <pre class="lang-cs prettyprint-override"><code>When(ReadyToDepart)
  .Request(TaxiToRunway,
                      (context) =&gt; context.Init&lt;TaxiToRunway&gt;(new {CorrelationId = context.Saga.CorrelationId}))
  </code></pre>
  <p>I am struggling to work out how to express this as part of a WhenEnter.</p>
  <pre class="lang-cs prettyprint-override"><code>WhenEnter(Taxiing, context =&gt; 
              context.Request(TaxiToRunway, c =&gt; c.Init&lt;TaxiToRunway&gt;(new {c.Saga.CorrelationId})));
  </code></pre>
  <p>Doesn't compile. There doesn't seem to be an overload for Request that works with message initializers. What should this look like?</p>
