title: Could not copy the file .xbf because it was not found
body: <p>When I build my project it gives me errors after the VS upgrade to 16.4.</p>
  
  <p>As per the Output window on the screenshot you can see now VS tries to refer to a path for xbf files that includes the namespace as well. Previously it was not.</p>

  <p>Eg: Previous path looks like this:
  C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Current\Bin\Microsoft.Common.CurrentVersion.targets(4570,5): error MSB3030: Could not copy the file "D:\AzureDevOps-Workspace\UWP\Main\PDFViewCtrlTools_VS2015\bin\x64\Debug\Utilities\SignatureDialog.xbf</p>
  
  <p>The new path has an additional folder, consists namespace of the class. “pdftron.PDF.Tools”.</p>
  
  <p>Why is this happening? On the old path, all the xbf files are available. But due to the new path reference VS gives errors like “it was not found.”</p>
  
  <p>I tried cleaning my solution, deleting all the bin and obj folder from all projects and rebuilding. Removing project references and readding it. Nothing works.</p>
