Question

Hi I am using WCF Rest in my app with a layered architecture. My dataflow heirarchy is given below:

Data Layer -> Linq2Sql
||
Business Layer
||
WCF Rest Service
||
ASPX Pages

I am using JSON via JQuery to Select/Delete and codebehind to Insert/Update so as I can pass .Net objects to database base through my business layer(to check if i have business logic for them.) using WCF servive.

Forexample , I am ciphering password and deciphering password in my business layer and sending it to datalayer.Anyways, thats not the Issue. The issue is with WCF service configurationsettings. Every time i am getting unique exceptions like:

1. 404 bad request.
2. There was no endpoint listening at http://localhost/Service.svc that could accept the message.
3. Could not find default endpoint element that references contract ‘xxx’ in the service model client configuaration section. This might be because no configuaration file was found for your application or because no end point element matching this contract could be found in the client element
   and so on….

What I tried is

1. As per answer suggested by Tom Haigh.
   protected Save_Click(sender,e)
   {

   var user = new User
   {
   Login = login.Value,
   Password = pwd.Value,
   RealName = realname.Value,
   AccessRight = accessrights.Value,
   CustomAccesRight = customaccessrights.Value
   };

       var remoteAddress = new EndpointAddress("http://localhost:2360/UserService.svc");
   
       using (var client = new UserServiceClient(new BasicHttpBinding(), remoteAddress))
       {
           //set timeout
           client.Endpoint.Binding.SendTimeout = new TimeSpan(0, 0, 0, 10000);
   
           //call ws method
           client.Insert(user);
       } //using
   

}

2. I removed using an tried also, got Error 400

   protected Save_Click(sender,e)
   {

   var user = new User
   {
   Login = login.Value,
   Password = pwd.Value,
   RealName = realname.Value,
   AccessRight = accessrights.Value,
   CustomAccesRight = customaccessrights.Value
   };

       var remoteAddress = new EndpointAddress("http://localhost:2360/UserService.svc");
   
      var client = new UserServiceClient(new BasicHttpBinding(), remoteAddress);
   
           //set timeout
           client.Endpoint.Binding.SendTimeout = new TimeSpan(0, 0, 0, 10000);
   
           //call ws method
           client.Insert(user);
   

}

My Config file of Service:

<system.serviceModel>
    <services>
      <service name="EnergyManagementControl.WcfSvc.UserService"  behaviorConfiguration="ServiceBehaviour" >
        <endpoint name="" binding="webHttpBinding"   contract="EnergyManagementControl.WcfSvc.IUserService" address="http://localhost:2360/UserService.Svc"   behaviorConfiguration="web"></endpoint>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehaviour"  >
          <serviceMetadata  httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="web">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
  </system.serviceModel>

My Config file of Client

<system.serviceModel>
    <client>
      <endpoint
        name = "Receptor"
         address="http://localhost:2360/UserService.Svc" 
        binding = "wsHttpBinding"
        contract="IUserService"
    />
    </client>
  </system.serviceModel>

But nothing seems to help. I know its config error ,please help me. Also any brief reference on WCF rest based on my scenario will be great help…..

Please not the WCF is created as a WCF Service Application and is a project in my Solution with my Web app. See image below:

Also I am getting error on WebDev Server,not on IIS or Cassini

Answer 1

I can’t speak much to WCF usage for REST services, but your service & client endpoint bindings do not match. WCF uses the binding to find a matching endpoint.
