I installed an ASP.NET application (.NET FW 4.0) on Windows Server 2019 and it works fine.
But when I try to update an application (just copy files to directory) then application do not want to start and it just tries to load. And after some multiple application pool recycling and w3wp.exe killing it starts working.
Same application update works correctly on previous version of Windows Servers.
Any suggestions why update stops the application ?
