title: Get path of a Solution Item file in Visual Studio Add-In
body: <p>I'm iterating through a solution and its projects and items and need to retrieve the path to the items on disk. </p>
  
  <p>I can retrieve the project file name from <code>Project.FullName</code> and can get a project items path using <code>ProjectItem.Properites.Item("FullPath")</code>.</p>
  
  <p>However, for an item in the solutions 'Solution Items' folder, the items Properties member is null and has no other properties which I can see could help me retrieve the path to the item. </p>
  
  <p>Although by default it will be located in the same directory as the solution when it is added I can't rely on this assumption as it could be moved or added as a pre-existing item from another location. </p>
  
  <p>Is there another way or something I'm missing to find the location of this file?</p>
