title: How to hide files generated by custom tool in Visual Studio
body: <p>I would like the files generated by my custom tool to be hidden, but I cannot find any documentation on how this is done.</p>
  
  <p>An example of what I'm looking for is WPF code behind files.  These files are not displayed in the Visual Studio project view, yet are compiled with the project and are available in IntelliSense.  WPF code behind files (Window1.g.i.cs, for example), are generated by a custom tool.</p>
