Method does not get executed properly in service mode in C#

Question

I have implemented a background service that executes some long process work. A snapshot of how the things are arranged are as follows:

 Task.Run(async () =>
          {             
              await DoBackgroundJob();
           });

public async Task DoBackgroundJob() {
        MatchAndInsertIntoDb(); // call another method
}

The method MatchAndInsertIntoDb has method signature as follows:

public ObservableCollection<Trucks> MatchAndInsertIntoDb() {

The issue is that when I put breakpoints on each line, the method MatchAndInsertIntoDb() gets executed properly, when I press F10 on each line.

But when the background service runs without debugging and breakpoints, the method MatchAndInsertIntoDb() does not seem to be executing properly. The method MatchAndInsertIntoDb() has a few methods in its body, like querying the local db and performing a match against another list and posting data on a remote web service.

My suspect is that since its a long-running operation, it is not getting sufficient time to complete the execution properly.

Could somebody enlighten me on this issue or help me to resolve it please ?

Ensuring that ` DoBackgroundJob();` gets completely executed. — ExpertGenie, Nov 30 '17 at 17:55
I think you misunderstand. You marked `DoBackgroundJob` as `async`, but there is no `await` in that method. So why is it marked `async`? — Kenneth K., Nov 30 '17 at 17:57
I am unable to await `MatchAndInsertIntoDb()` as its signature is not `async`. — ExpertGenie, Nov 30 '17 at 17:58
If you do not do anything asynchronous in DoBackgroundJob then you should not add `async` or `Task` as the result. That is not how async/await works.... — Igor, Nov 30 '17 at 18:02
I am adding Task to the method and async so as not to block the main UI thread. — ExpertGenie, Nov 30 '17 at 18:04

@Igor : Should all methods within the `MatchAndInsertIntoDb()` be of type `async` and all these corresponding methods should have await ? — ExpertGenie, Nov 30 '17 at 18:18
