title: how to call renderpartial from spark
body: <p>I'm using both spark and .aspx view engines. My partial is in aspx so i'm tring to call from my spark engine. </p>
  
  <p>I've seen something like the following</p>
  
  <p>${Html.RenderPartial("HeaderControl")}</p>
  
  <p>Seems like i'm missing a reference, can't really see what. </p>

    using directive or an assembly
    reference?)</p>
