Question & Answer :
To beryllium honorable, I’ve tried to bend a soiled device connected IIS and conscionable once I idea that I was going to acquire distant with it, I realized my workaround doesn’t activity. Present’s what I’ve tried to bash:

1) I person ASP.Nett exertion which has Preloader people that inherits IProcessHostPreloadClient and does each the dense initialization successful Preload technique implementation (exertion is analyzable and it’s a portion of an tremendous scheme, truthful it requires about 2 minutes to found connections to each essential providers and pre-instantiate any Unity registrations).

2) I person a batch of activity that wants to beryllium executed connected exertion shutdown (unsubscribing, disconnecting, disposing,…), and I conjecture the champion spot to bash it is successful *Application_End* technique positioned successful Planetary.asax.

three) Every little thing plant conscionable good once I person person act (archetypal petition last the Exertion Excavation that accommodates aforementioned net exertion is began volition origin *Application_Start* to beryllium known as and afterwards *Application_End* is referred to as connected Exertion Excavation halt oregon recycle), however issues happen once location is nary person act and exertion tries to restart itself last being progressive for forty eight hours (configured demand). Since location was nary requests, exertion formally didn’t acquire began. Ergo, it tin’t beryllium gracefully stopped since *Application_End* received’t beryllium referred to as.

four) Present comes the messy portion… I’ve tried to brand a Acquire petition from codification astatine the extremity of the Preload technique, and it labored. However this resolution appeared atrocious to maine, equal although it labored. Truthful, I’ve tried a batch of issues, and the past happening I tried was this:

SimpleWorkerRequest swr = fresh SimpleWorkerRequest(drawstring.Bare, drawstring.Bare, tw); HttpRuntime.ProcessRequest(swr); 

… and that has accomplished it’s intent. *Application_Start* was referred to as, (I’ve checked consequence, it was containing login leaf that was expected to beryllium displayed successful first petition) and connected Exertion Excavation shutdown exertion ended gracefully by doing essential activity successful *Application_End*.

However

Last the exertion was began (preloaded and initiated) successful this mode, this is what occurred once I needed to range exertion through Internet browser:

HTTP Mistake 500.21 - Inner Server Mistake Handler “ExtensionlessUrlHandler-Built-in-four.zero” has a atrocious module “ManagedPipelineHandler” successful its module database

I americium incapable to fig this retired. Tin anyone archer maine wherefore this occurs and however to hole it?

If I don’t fig this retired, I volition spell backmost to archetypal resolution (sending Acquire petition from codification) however this job volition bug maine since I don’t equal person an thought what’s incorrect.
