title: Cant convert website to webapplication in Visual Studio 2019
body: <p>I am trying to convert an old Visual Basic web site project, into a web application, using VS2019.
  I have tried following this:</p>
  <p><a href="https://devblogs.microsoft.com/aspnet/converting-a-web-site-project-to-a-web-application-project/" rel="nofollow noreferrer">https://devblogs.microsoft.com/aspnet/converting-a-web-site-project-to-a-web-application-project/</a></p>
  <p><a href="https://docs.microsoft.com/en-us/previous-versions/aa983476(v=vs.140)?redirectedfrom=MSDN" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/previous-versions/aa983476(v=vs.140)?redirectedfrom=MSDN</a></p>
  <p>However, when I copy the remaining files (after converting app_code) and try to convert it to a webapplication, it is unable to parse any of the aspx files. I haven't been able to find the reason for this. Do any one have any ideas?</p>
  <p>Thank you.</p>
