Question

I am just starting to learn how Task works, and get one interesting case.
I have HttpTaskAsyncHandler but I can’t get acccess to HttpContext if my code inside ProcessRequestAsync calls to some Task

  public class MyAsyncHandler : HttpTaskAsyncHandler, IReadOnlySessionState
    {
        public override async Task ProcessRequestAsync(HttpContext context)
        {
            //can use HttpContext here   
            await MyJob("data");
            //can use HttpContext here
        }

      public async Task MyJob(string data)
        {
            var func = Task.Factory.StartNew(() => Process(data));
            await func;
        }

        public string Process(string context)
        {
             **//can't use HttpContext here**
            Elmah.ErrorSignal.FromCurrentContext().Raise(ex);   
        }
}

is it possible to fix ? I understand that Process method would be call in other tread but anyway.
Thanks/

Answer 1

You are correct that HttpContent does not exist inside of your Task, since it is in a separate thread. So you will need to access create a new instance of Elmah inside your Process method(new thread). You can follow the 2nd or 3rd answer in the previous question, Using Elmah in a Console Application to accomplish what you want.
