wcf error

Hi,
I have been battliing with an issue with wcf and wonder if anyone can solve my issue.

Many thanks

In a silverlight apllication, I created a wcf service under the host i.e. (projectname.web) project. Then from the silverlight application which holds all the .xaml pages, I reference the wcf and all works fine (The wcf is calle dfrom the .xaml and data is retrieved).

Problem is arised only when I try to separate the wcf service from the webhost i.e. (projectname.web). So I created a separate wcf service application project and then tried to call the service from the .xaml project.
The error I get is in references.cs
The error message is: The remote server returned an error: NotFound.

and the code which causes the error is:

public Samples.ProductServiceHost.Product EndGetProduct(System.IAsyncResult result) {
object[] _args = new object[0];
Samples.ProductServiceHost.Product _result = ((Samples.ProductServiceHost.Product)(base.EndInvoke("GetProduct", _args, result)));
return _result;
}

I have also added the crossdomain.xml to the wcf service application project.
I wonder if the error is to do with the web.config.

This is what the web.config looks like in the wcf service application:

<?xml version="1.0"?>
<configuration>

<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<services>
<service behaviorConfiguration="Samples.Services.ServiceBehavior"
name="Samples.Services.ProductService">
<endpoint address=""
binding="basicHttpBinding"
contract="Samples.Services.IProductService">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint address="mex"
binding="mexHttpBinding"
contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="Samples.Services.ServiceBehavior">
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>

</configuration>

The not-found error implies the your URL is not correct. I can see that you have no adress in the web.config, that is, I think, part of the probem:

vb Code:

<endpoint address="" [B]<--- MISSING[/B]
binding="basicHttpBinding"
contract="Samples.Services.IProductService">
