Asynchronous Callbacks. Delegates can also be used as CallBacks. CallBacks are used in many Windows API calls. You pass in a function pointer to the API call. When the API call gets finished with it's job, it then âcalls backâ to the function via the function pointer you passed it. This allows your code to know when the API call is done.
Async methods that return void are intended for event handlers; in most cases where a synchronous method would return void, returning Task instead is recommended, as it allows for more intuitive exception handling. Methods that make use of await must be declared with the async keyword. In methods that have a return value of type Task<T>, methods declared with async must have a return statement of type assignable to T instead of Task<T>; the compiler wraps the value in the Task<T> generic.
