WCF：无法找到端点引用

Question

I am working on a SharePoint 2013 webpart and a label on the webpart needs to communicate with a SQL Server data table using WCF. I have created the WCF interface and main class, and have also invoked the service in my Visual webpart like this:

protected void Page_Load(object sender, EventArgs e)
    {
        WcfServiceReference1.Service1Client client = new WcfServiceReference1.Service1Client();
        CustomerNameLbl.Text = client.GetCustomerName(ProjectIDDescLbl.Text);
    }

Where WcfServiceReference1 is the added WCF service reference and a customer label text is being changed depending on the project number label. The project builds and deploys fine but when I add the webpart, I get this error: Could not find default endpoint element that references contract 'WcfServiceReference1.IService1' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

My app.config file is this:

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_IService1" />
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://as-sv-dev02:2345/Service1.svc" binding="basicHttpBinding"
            bindingConfiguration="BasicHttpBinding_IService1" contract="WcfServiceReference1.IService1"
            name="BasicHttpBinding_IService1" />
    </client>
</system.serviceModel>

And web.config file (for SharePoint) is this:

<system.serviceModel>
<bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_IService1" />
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://as-sv-dev02:2345/Service1.svc" binding="basicHttpBinding"
            bindingConfiguration="BasicHttpBinding_IService1" contract="WcfServiceReference1.IService1"
            name="BasicHttpBinding_IService1" />
    </client>

Can anyone guide me on how to resolve this? Am I going wrong somewhere?

After a lot of research, I found out that there was some problem with SharePoint which I don't really understand. Thankfully, in time, I chose not to go the SharePoint way and instead work with a simple .aspx page and that would resolve the issue. Just unhappy with Microsoft not offering as much support on such common issues.

I had the same problem and I found this link.

I did it and worked fine. The problem is the deploy does not copy the service model configuration from the Visual Studio' app.config to the IIS's web.config.

I hope helps.

Best Regards.

Your client endpoint does not seem to have a default configuration (name="" or nameless). Try using:

WcfServiceReference1.Service1Client client = new WcfServiceReference1.Service1Client("BasicHttpBinding_IService1");
