i getting HTTP Error 404 after upgrade my application from .Net 5 to .Net 8. API side is running fine but Client side having error. I tried to create new application and copy the launchSetting from existing project to the new project and new project running fine. I had also update my dependencies to latest version but somehow it’s not working. Anyone facing the same issue that can advise?
