使用c＃进行异步编程-async，await和Task.Run

Question

class Program
{
    static void Main(string[] args)
    {
        AsyncWithWait();
        //Console.WriteLine(s.Result);
        Task.Run(() => AsyncWithOutWait());
        Console.WriteLine("Main End");
        Console.ReadLine();

    }
    public static void AsyncWithOutWait()
    {
        Thread.Sleep(3000);
        Console.WriteLine("AsyncWithOutWait");
    }

    public static async Task AsyncWithWait()
    {
        await Task.Delay(5000);
        Console.WriteLine("AsyncWithWait");
    }
}

Is there any difference between the way AsyncWithWait and AsyncWithOutWait in the above implementation?

The output is as expected but I would like to know the proper way to implement Asynchronous programming.

Output

Main End
AsyncWithOutWait
AsyncWithWait

AsyncWithWait doesn't block a thread just waiting for the time period; AsyncWithOutWait does.

Use async and await . To understand more how it works, read my intro to async post.
