找不到引用合同的默认端点元素 - 托管wcf

Question

I have one wcf service on this site http://wswob.somee.com/wobservice.svc

I try to consume that service with my winform app. This is the error I receive when I create an instant of the service

com.somee.wobservice.IwobserviceClient myservice = new com.somee.wobservice.IwobserviceClient();

error:

Could not find default endpoint element that references contract
'com.somee.wobservice.Iwobservice' 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.

I searched and modified my app.config file:

<system.serviceModel>
<behaviors>
  <endpointBehaviors>
    <behavior name="wobservice">
      <clientVia />
    </behavior>
  </endpointBehaviors>
</behaviors>

<client>
  <endpoint
      name="wobservice"
      address="http://wswob.somee.com/wobservice.svc"
      binding="webHttpBinding"
      contract="com.somee.wobservice"
      behaviorConfiguration="wobservice" />
</client>

</system.serviceModel>
</configuration>

And my web.config in wcf folder:

<system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true"/>

          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>

        <endpointBehaviors>
            <behavior name="Web">
                <webHttp/>
            </behavior>
        </endpointBehaviors>
    </behaviors>

      <serviceHostingEnvironment  multipleSiteBindingsEnabled="true">
          <baseAddressPrefixFilters>
              <add prefix="http://wswob.somee.com/"/>
          </baseAddressPrefixFilters>
      </serviceHostingEnvironment>

      <bindings>
          <webHttpBinding>
              <binding>
                  <security mode="None" />
              </binding>
          </webHttpBinding>
      </bindings>

      <protocolMapping>
           <add binding="basicHttpsBinding" scheme="https"/>
           <add binding="basicHttpBinding" scheme="http"/>
      </protocolMapping>

      <services>
           <service name="wobwcf.wobservice">
              <endpoint address="" 
                        binding="webHttpBinding" 
                        behaviorConfiguration="Web" 
                        contract="wobwcf.Iwobservice" />
           </service>
      </services>
   </system.serviceModel>

I don't really sure which part I got wrong. My experience of wcf is just a week...

Answer 1

Copy system.serviceModel section from the app.config in your library project and put it in your web.config and refresh service reference. See also this answer. Could not find default endpoint element

Answer 2

Add "WSHttpBinding" end point in your WCF service web.config file like below

 <endpoint address="web" behaviorConfiguration="jsonBehavior" binding="webHttpBinding" bindingConfiguration="webHttpBindingWithJsonP" contract="DataService.IDataService"/>
 <endpoint address="" binding="wsHttpBinding" bindingConfiguration="wsHttpBinding" contract="DataService.IDataService"  />

and in your app.config file write code like below

<system.serviceModel>
<bindings>
  <wsHttpBinding>
    <binding name="WSHttpBinding_IDataService" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647">
      <security mode="None" />
    </binding>
  </wsHttpBinding>
</bindings>
<client>
  <endpoint address="http://localhost/pricedataservice/DataService.svc" binding="wsHttpBinding"
      bindingConfiguration="WSHttpBinding_IDataService" contract="DataService.IDataService"
      name="WSHttpBinding_IDataService" />
</client>

I am sure this will fix your problem and below blog will help you to understand different type of binding in WCF service

Answer 3

Add client definition in your client web.config file like below;

 <system.serviceModel>
  /////
 <client>
         <endpoint  address="referencedurl"
          binding="webHttpBinding" bindingConfiguration=""
          contract="MemberService.IMemberService"
          name="MemberServiceEndPoint"
          behaviorConfiguration="Web">
      </endpoint>
 </client> 
////
 </system.serviceModel>

AND Service Reference Name must same as the Interfaces prefix. contract=" ReferenceName .IMemberService"
