title: Adding Solution Items in a project template wizard
body: <p>I'm trying to add a file to a Visual Studio "Solution Items" folder, using a Project Template Wizard. I'm able to create the folder itself, but when I add a file, it doesn't do anything. </p>
  
  <p>My code (executed from <code>ProjectFinishedGenerating</code>) is</p>
  
  <pre><code>    fullPath = @"path_to_existing_file";
      _solutionFolder.AddFromFile(fullPath);
  </code></pre>
  
  <p>Where _solutionFolder is a Project instance corresponding the the solution folder. </p>
