Exception - How To Safely Call An Async Method In C# Without Await - Stack Overflow. We test a call to interlocked.increment in the second loop. Foocontroller.getfoo and fooservice.getfooasync just return another task without doing anything else.

Methodcallwithoutawait will be called, however no exception will be raised in the debugger. What happens when you call. Continuewith (t => console.writeline (t.exception), taskcontinuationoptions.onlyonfaulted); You need to decide if you want that or not. Also, try to code async all the way trough, make every async method call and be called from async methods. It is much easier just refactor out your error handling in to a method and put it in there, then you can just call that new method from your main method. You can safely make the method async and await your call to the database. In your example, that probability is 100%. If there’s a synchronous version of a library method already available and it will complete quickly, consider using that instead. Best practice would be to change the return type to task.
Runsynchronously is invalid to use because not all tasks can be processed that way.getawaiter().getresult() is different from result/wait() in that it mimics the await exception propagation behavior. In earlier c# versions, to ensure that the main method waits for the completion of an asynchronous operation, you can retrieve the value of the task.result property of the task instance that is returned by the corresponding async method. Add a comment | 1 answer sorted by: Best practice would be to change the return type to task. If you call an async method from a single threaded execution context, such as a ui thread, and wait for the result synchronously, there is a high probability for deadlock. } catch (exception ex) { trace.writeline(ex); What happens when you call. Also, try to code async all the way trough, make every async method call and be called from async methods. This is the solution to catch exceptions in asynchronous methods. On the page for that warning it states: //dostuff without waiting for result //do a wait at the end to prevent the program from closing before the background work completes.
