Windows phone 8 CommunicationException The remote server returned an error: NotFound

Question

I want to ask a question that make me crazy all this time @_@ I've made an app for windows phone 8 which retrieve data from wcf service. Luckily, my office mate make me a service for it. But, when I use that service, I got this error.

After Searching here and there, I got this good article. http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj684580(v=vs.105).aspx

But, I read it and still don't get it. Why? Because my service is write in C# class, not as a web service. So i can't found the IIS service.

Here is my code to generate my data.

public PurchaseInvoiceMainPage()
        {
            InitializeComponent();
            this.Loaded += new RoutedEventHandler(purchaseInvoice_Loaded);
        }

        private void purchaseInvoice_Loaded(object sender, RoutedEventArgs e)
        {
            NavcoreNavfinServiceClient client = new NavcoreNavfinServiceClient();
            client.GetAllCompleted += new EventHandler<GetAllCompletedEventArgs>(client_getAllPurchaseInvoice);
            client.GetAllAsync("509A7214-D3A9-47E7-9BB4-232E670ED650");
        }

        private void client_getAllPurchaseInvoice(object sender, GetAllCompletedEventArgs e)
        {
            if (e.Error == null)
            {
                purchaseDataList.ItemsSource = e.Result;
            }
        }

And, here is my service which return the result.

public System.Collections.ObjectModel.ObservableCollection<NavFinance.NavFinData.vwPurchaseInvoice> EndGetAll(System.IAsyncResult result) {
                object[] _args = new object[0];
                System.Collections.ObjectModel.ObservableCollection<NavFinance.NavFinData.vwPurchaseInvoice> _result = ((System.Collections.ObjectModel.ObservableCollection<NavFinance.NavFinData.vwPurchaseInvoice>)(base.EndInvoke("GetAll", _args, result)));
                return _result;
            }

I got the Exception right on this line.

System.Collections.ObjectModel.ObservableCollection<NavFinance.NavFinData.vwPurchaseInvoice> _result = ((System.Collections.ObjectModel.ObservableCollection<NavFinance.NavFinData.vwPurchaseInvoice>)(base.EndInvoke("GetAll", _args, result)));

I've used many trick that i found, starting from upsizing the maxbytes, etc. It still does not work. Some one please help me. I really confuse TT_TT

Here is the service that i use.

Answer 1

This error indicates that your application was unable to communicate with the service. are you try the service URL in the phone/emulator Internet Explorer to be sure the url is accessible?

Answer 2

woah, amazing..!! after 3 days suffering about this error, finally found something. :)

All the credit should be given to Josue Yeray Thanks a lot man, why I am not realize about that erlier. Finally i got my data from my service only by connecting the emulator to the internet.

In my case, usually i used wired connection, and that's not working at all at the emulator. after searching, i change my connection to wireless connection. and then, its working and done.

Thanks a lot. :)

Answer 3

Do nothing Extra, Just go and turn off the Firwall of Public and Private both, then wait for 2-3 mins and then run the App. It will run perfect.

I did and it worked.
