title: .Net framework 4 SDK download URL?
body: <p>You used to be able to download a neatly packaged .Net framework SDK, which had the framework + developer tools (other than Visual Studio of course).  What's the equivalent for .Net 4?</p>
  
  <p>The reason I ask is that I need to upgrade my build server to build .Net 4 code, and I don't want to install Visual Studio on it.</p>
