HttpRuntime.UnloadAppDomain Method ()
Terminates the current application. The application restarts the next time a request is received for it.
Assembly: System.Web (in System.Web.dll)
UnloadAppDomain is useful for servers that have a large number of applications that infrequently receive requests. Rather than keep application resources alive for the lifetime of the process, UnloadAppDomain allows programmatic shutdown of unused applications.
