title: asp.net ScriptManager and UpdatePanel controls missing
body: <p>I have created a new ASP.NET Web Application, but the controls for ScriptManager and UpdatePanel are missing. After a fair bit of googling, and messing with the web.config, I am unable to get them installed properly.</p>
  
  <p>I have another project in which they are installed and working, and I have copied all of the code from web.config across, but still no luck.</p>
  
  <p>Maybe Visual Studio has a tool for installing it automatically?! Or is that wishful thinking?!</p>
