title: Add created class file to project
body: <p>I have a console application that builds some default classes for me from a database. When the files are built, I want to be able to refresh my folders and see the new files in my class library. </p>
  
  <p>However no matter what I do the files don't show up unless I go in and manually add existing files.  Is there a way for VS2010 to look at the file folder and add in anything that is in that folder to the project?  For example:</p>
  
  <blockquote>
    <p>Folder > File1.cs, File2.cs, File3.cs, File4.cs</p>
  </blockquote>
  
  <p>VS2010 sees</p>
  
  <blockquote>
    <p>Folder > File1.cs</p>
  </blockquote>
  
  <p>How can I make VS2010 show these new classes?</p>
