Difference between Task.Run and QueueBackgroundWorkItem in Asp.Net

Question

What exactly is the difference using

Task.Run(() => { 
     LongRunningMethod();
});

or

HostingEnvironment.QueueBack         


        

Answer 1

The AppDomain shutdown can only be delayed 90 seconds (It’s actually the minimum of HttpRuntimeSection.ShutdownTimeout and processModel shutdownTimeLimit). If you have so many items queued that they can’t be completed in 90 seconds, the ASP.NET runtime will unload the AppDomain without waiting for the work items to finish.
