Application unable to find a web service when hosted remotely on IIS7

06-06-2009 4:04 PM |

I am unable to move my Silverlight application from my development environment to the web site host. I am switching the <endpoint address> before uploading the app. I have followed very closely the steps laid out at http://msdn.microsoft.com/en-us/library/cc197964(VS.95).aspx but with no luck.

The application works correctly locally but when moved to my web site host there is an error.

Here is a picture of the VS8 solution environment: http://www.labelease.com/SilverLightQuestion/DevEnv.png

The error:

The Silverlight application renders but the service, Service1, cannot be found. The result code returned and viewed in Fiddler is 500. The service when it works returns an int of value 2.

Development environment:

VStudio 2008 SP1

Silverlight 2.0

host: DiscountASP.net IIS 7

Fiddler

Note: These MIME extensions have been added to IIS 7 at DiscountAsp.net

.xap application/x-silverlight-app

.xaml application/xaml+xml

.xbap application/x-ms-xbap

// This is the Service.

using System.ServiceModel;

using System.ServiceModel.Activation;

namespace NR3.Web

{

[ServiceContract(Namespace = "")]

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

public class Service1

{

// Add more operations here and mark them with [OperationContract]

[OperationContract]public int GetThis()

{

return 2;

}

}

// This is the client.

using System;

using System.Windows.Controls;

using System.ServiceModel;

using NR3.ServiceReference1;

namespace NR3

{

public partial class Page : UserControl

{

public Page()

{

InitializeComponent();

Service1Client proxy = new Service1Client();

proxy.GetThisCompleted +=

new EventHandler<GetThisCompletedEventArgs>

(proxy_GetThisCompleted);

proxy.GetThisAsync();

}

void proxy_GetThisCompleted(object sender,GetThisCompletedEventArgs e)

{

//throw new NotImplementedException();

this.userCountResult.Text ="Number of users = " + e.Result;

}

// This is the ServiceRerences.ClientConfig configured for DiscountAsp.net hosting
<configuration>

<system.serviceModel>

<binding

name="BasicHttpBinding_Service1"

maxBufferSize="2147483647"

maxReceivedMessageSize="2147483647"

closeTimeout="00:59:00"

openTimeout="00:53:00"

receiveTimeout="00:15:00"

sendTimeout="00:21:00">

</binding>

</basicHttpBinding>

</bindings>

<endpoint address="http://www.myWebSite.com/Service1.svc"

binding="basicHttpBinding"

bindingConfiguration="BasicHttpBinding_Service1"

contract="ServiceReference1.Service1"

name="BasicHttpBinding_Service1" />

</client>

</system.serviceModel>

</configuration>

// Here is Page.xaml

<UserControl x:Class="NR3.Page"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Width="400" Height="300">

</StackPanel>

</Grid>

</UserControl>

If anybody can point what I'm missing it is greatly appreciated.

Thanks ... Neil

Hi,

DiscountAsp.net is a shared hosting environment, you have to use a ServiceHostFactory. Read these threads/articles for more details:

Still no luck.

I've edited Service1.svc to this

<%@ ServiceHost Factory="NR3.Web.myHostFactory" Language="C#" Debug="false" Service="Service1" CodeBehind="Service1.svc.cs" %>

And added this class, a HostFactory.

namespace NR3.Web

{

public class myHostFactory : ServiceHostFactory

{

protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)

{

// Specify the exact URL of your web service

var webServiceAddress = new Uri("http://www.myWebSite.com/Service1.svc");

var webServiceHost = new ServiceHost(serviceType, webServiceAddress);

return webServiceHost;

}

Absolutely no luck/change.

I'm stuck!

Tried that a week ago. Fails on step 1. Can't find the service or service is not running.

Thanks... Neil

Well, I finally figured it out. Thanks Davide for the direction toward the ServiceHostFactory. MSDN link is here: http://msdn.microsoft.com/en-us/library/aa702697.aspx

The error I encountered implementing the ServiceHostFactory is detailed below:

This is the correct line of code that appears in Service.sc

<%@ ServiceHost Factory="NR3.Web.myHostFactory" Language="C#" Debug="false" Service="NR3.Web.Service1" CodeBehind="Service1.svc.cs" %>
