I just copied an asp.net v2 app (.net v2) from a win2003 box to a new server2016 box.
When I hit the app url on the server2016 box, I get this error:
HTTP Error 404.3 - Not Found
The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.
What is missing in my server2016 iis env to resolve this? (Seems like the aspx handler should already be there! I think I installed all the relevant IIS pieces.)
