WCF Exercise


Scenario
Ultimate Lottery and Gaming (ULG) wants to build a WCF application that allows the client application at the ticket vendor to retrieve winning number of a given lottery draw. 

Task 1:
Create a WCF service that exposes a method called GetWinningNo that takes a string parameter and returns an object of type Draw. Use the following two partially completed classes: 

    public class Draw
    {
        public string Id { get; set; }
        public int [] WinningNo { get; set; } 
        public double PoolAmt { get; set; }
    }


    public class LottoSrv
    {
        Dictionary<string, Draw> drawList = new Dictionary<string, Draw>();

        public LottoSrv()
        {
            int [] w1 = { 1, 2, 3, 4, 5, 6, 7 };

            drawList.Add("649-29jun16",
                new Draw(){Id="649-29jun16",WinningNo = w1, PoolAmt=1000000});
            drawList.Add("649-25jun16",
                new Draw() { Id = "649-25jun16", WinningNo = w1, PoolAmt = 1200000 });
        }

        public Draw GetWinningNo(string drawId)
        {
            return drawList[drawId];
        }
    }

Note: GetWinningNo() is the method that needs to be exposed to the client. 

Task 2:
Host the service that you created in Task 1, in a console application.

Task 3:
Create client that consumes the service exposed by the Host in Task 2. Use the partially completed code given below:

        static void Main(string[] args)
        {
         
            Draw d1 = client.GetWinningNo("649-25jun16");

            Console.Write("ID: {0} \nPool Amount: {1} \nWinning No: ", d1.Id, d1.PoolAmt );
            foreach (var item in d1.WinningNo)
            {
                Console.Write(item + " ");
            }

            Console.ReadLine();
        }

Test to ensure that the solution works as shown below:
