title: Determination of the work mode with the project in Visual Studio 2017
body: <p>In Visual Studio 2017 it is possible to work in a mode ‘Folder View’. This is the mode that runs when opening folder (File – Open – Folder...). You can also switch to it using the 'Solution Explorer' (switching from a 'Solution View' to 'Folder View').</p>
  
  <p>Is it possible to programmatically determine (and if so, then how) what mode is enabled at the moment?</p>
  
  <p>I saw the <code>IVsSolutionEvents7</code> interface, which contains methods that are called, for example, when opening or closing a folder (File – Open – Folder / Close Folder), but have not found anything that would help in addressing the problem described above.</p>
  
  <p>Thanks in advance for your help.</p>
