title: Why doesn't the "Namespace Provider" property get saved within a project file for a given subdirectory?
body: <p>Sub directories within VS2008 projects are mainly used to physically represent on disk the namespace structure for the project. Each folder has a Boolean property called “Namespace Provider”, which when set to True causes ReSharper to validate that the physical location of a given class corresponds to the logical namespace location.</p>
  
  <p>Occasionally I don’t want a folder to be used as a Namespace Provider, so I set this property to False, and ReSharper doesn’t perform the check.</p>
  
  <h3>Problem</h3>
  
  <p>This setting doesn’t get saved in the project file, and therefore reverts to the default value of True next time I open the solution. It’s not that big a deal but ReSharper does give you lots of warnings about incorrect namespaces.</p>
  
  <p>Why doesn’t the property value get saved?</p>
  
  <h3>Versions...</h3>
  
  <p>ReSharper 4.0 with VS2008 SP1</p>
