There's two ways to deploy a .NET Core application. There's FDD and SCD. Since TLAs (three letter acronyms) are stupid, that's Framework-dependent and Self-contained.

ASP.NET 2.0 introduced a concept of application offline. This mean that when there is App_Offline.htm file in the root of a web application directory then ASP.NET will shut-down the application, unload the application domain from the server, and stop processing any new incoming requests for that application.

As of April 1, 2020 Log4Net is a dormant project of Apache Logging Services. The dormant status means the project has been classified as inactive since it has had no recent development activity and there are no active volunteers to perform code reviews, commit code, or perform releases. Although it is possible volunteers might choose to participate in the future, it is best to assume there will be not future development or releases.
