Async & await keyword in C#

CsharpServer Side ProgrammingProgramming

The async and await keyword is used in C# for asynchronous programming.

An application with a GUI, check the content of the queue and if an unprocessed task is there, it takes it out and processes it first. The code executes synchronously and the unprocessed task is completed first. The application will show stop responding to messages if the processing takes more time than expected.

Let us see what is discussed above −

private void OnRequestDownload(object sender, RoutedEventArgs e) {
   var req = HttpWebRequest.Create(_requestedUri);
   var res = req.GetResponse();

To solve the above issue, use the async and await keywords −

private async void OnRequestDownload(object sender, RoutedEventArgs e) {
   var req= HttpWebRequest.Create(_requestedUri);
   var res = await req.GetResponseAsync();
