simple example of async saving time

    static async Task<string>  blah()

        {

            await Task.Delay(5000);

            return "blah " + DateTime.Now.ToString();  

        }

        static async Task<string> masterblah()

        {

            Task<string> a =  blah();

            Task<string> b =  blah();

            Task<string> c =  blah();

            string a1 = await a;

            string b1 = await b;

            string c1 = await c;

            Console.WriteLine( string.Format("{0}-{1}-{2}", a1, b1, c1));

            return string.Format("{0}-{1}-{2}", a1, b1, c1); 

        }

       

        static void Main(string[] args)

        {

            Console.WriteLine(DateTime.Now);

            masterblah();
