title: Can you use Interop Assemblies with Office 365 client apps?
body: <p>With Office 2010/2013 you could download the PIA Primary Interop Assemblies and do stuff that would control Excel etc, like building an ad-hoc spreadsheet.</p>
  
  <pre><code>Add-Type -Assembly "Microsoft.Office.Interop.Excel" 
  $app = New-Object Microsoft.Office.Interop.Excel.ApplicationClass
  </code></pre>
  
  <p>Does the same thing work with the Excel in Office 365?</p>
