title: what is the difference between web deployment tool 2.1 and web deploy 3.5? which one is required for deploys from VS 2010?
body: <p>I am trying to setup publishing/deployment of an asp.net mvc project from visual studio to a box running IIS 7.5/Windows Server 2008. I found <a href="http://web.archive.org/web/20121005054118/http://tedgustaf.com/en/blog/2011/8/publish-aspnet-website-through-visual-studio-to-remote-server-using-web-deploy/" rel="noreferrer">this</a> useful tutorial and know I need to install something called web deploy. </p>
  
  <p>When I go to install this from Web Platform Installer I see a few options: web deployment tool 2.1, web deploy 3.5 and 
   web deploy 3.5 for hosting servers. </p>
  
  <p>Which one do I need? What is the difference?</p>
