title: Why did my css not work until added to project?
body: <p>I have an asp.net mvc project, and I replaced the default css the wizard built with the iui css and javascript package.  They were placed in ~/Content/iui/ folder.  When i ran the site through the dev web server, the css didnt get used.  I managed to fix it by adding the iui folder to the project in the project explorer.  That's all I did, the pages already the script and style tags set up properly.</p>
  
  <p>What is going on here?  I'm sure MSVS is up to something behind the scenes, and I'd like to understand why it did this and why what I did produced the behaviour that it did.</p>
