Calling Async Call from Main()

This is a small code which shows different ways of calling an async method inside Main

Following is my sample method.

1. public async Task<int>SampleMethod()
2.     {
3.         await Task.Delay(5000);
4.         int answer = 21 * 2;
5.         return answer;
6.     }

 

1. Using  GetAwaiter()

 

1. static void Main(string[] args)
2.     {
3.         SampleMethod().GetAwaiter().OnCompleted(() =>
4. {
5.     Console.WriteLine("finished");
6. });
7.         Console.ReadKey();
8.     }

 

2. Using  Wait()

1. static void Main(string[] args)
2.     {
3.         SampleMethod().Wait();
4.     }

 

Hope this helps,
