title: Comparing Castle Windsor, Unity and StructureMap
body: <p>In a follow up to <a href="https://stackoverflow.com/questions/388355/castle-windsor-are-there-any-downsides/397461#397461">Krzysztof’s statement</a> that <a href="http://www.castleproject.org/container/index.html" rel="nofollow noreferrer">Windsor</a> does a lot more than other IoC’s, I wanted to understand how these IoC’s stack up against each other and the benefits/additional facilities that castle Windsor provides.  </p>
  
  <p>Are there any comparisons? Can someone help me understand the additional features that Castle Windsor provides over other IoC’s   </p>
