You check in Web.config of the client if contains a endpoint configuration?

i have used your application but i am getting error like Could not find default endpoint element that references contract 'IChat' 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.

Your client must contain a same code in your Web.config or App.config:

<system.servicemodel>
    <bindings>
      <basichttpbinding>
        <binding name="basicHttpEndPointConfiguration" closetimeout="00:01:00">
          openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
          allowCookies="false" bypassProxyOnLocal="false"                   hostNameComparisonMode="StrongWildcard"
          maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
          messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
          useDefaultWebProxy="true">
          <readerquotas maxdepth="32" maxstringcontentlength="8192" maxarraylength="16384">
            maxBytesPerRead="4096" maxNameTableCharCount="16384" />
          <security mode="None">
            <transport clientcredentialtype="None" proxycredentialtype="None">
              realm="" />
            <message clientcredentialtype="UserName" algorithmsuite="Default" />
          </transport></security>
        </readerquotas></binding>
      </basichttpbinding>
    </bindings>
    <client>
      <endpoint address="http://localhost/YourService.svc">
        binding="basicHttpBinding" bindingConfiguration="basicHttpEndPointConfiguration"
        contract="WCF.IYourService" name="basicHttpEndPointConfiguration" />
    </endpoint></client>
  </system.servicemodel>

// wcf-wpf client-host project run properly but when i imported this project //into my own small project then client stopped working and give exception.
" Could not find default endpoint element that references contract 'SVC.IChat' 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. "

/// this how my app.config file is:
