Tasks executed by calling the RunSynchronously method are instantiated by calling a Task or Task class constructor. The task to be run synchronously must be in the Created state. A task may be started and run only once. Any attempts to schedule a task a second time results in an exception.Click to see full answer. In respect to this, how do you call a synchronous method asynchronously in C#?The simplest way to execute a method asynchronously is to start executing the method by calling the delegate’s BeginInvoke method, do some work on the main thread, and then call the delegate’s EndInvoke method. EndInvoke might block the calling thread because it does not return until the asynchronous call completes.Likewise, what is the use of await in C#? The await operator suspends evaluation of the enclosing async method until the asynchronous operation represented by its operand completes. When the asynchronous operation completes, the await operator returns the result of the operation, if any. Regarding this, is await synchronous? Async/await makes your code look synchronous, and in a way it makes it behave more synchronously. The await keyword blocks execution of all the code that follows until the promise fulfills, exactly as it would with a synchronous operation.Can we use await without Async in C#?Every now and then you’ll find yourself in a synchronous method (i.e. one that doesn’t return a Task or Task ) but you want to call an async method. However, without marking the method as async you can’t use the await keyword. But in most cases, I recommend against using async void .
