winform里直接使用WCF，不需要单独的WCF项目

依照此法建立即可，

但是vs生成的配置有误，正确配置如下

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <behaviors>
            <serviceBehaviors>
                <behavior name="">
                    <serviceMetadata httpGetEnabled="true" />
                    <serviceDebug includeExceptionDetailInFaults="false" />
                </behavior>
            </serviceBehaviors>
         <!-- 以下需要手工添加-->
          <endpointBehaviors>
            <behavior name="webBehavior">
              <webHttp/>
            </behavior>
          </endpointBehaviors>
         <!-- 以上需要手工添加-->
        </behaviors>
        <services>
            <service name="WindowsFormsApplication1.Service1">
         <!-- binding 值需要改为webHttpBinding 并增加 behaviorConfiguration="webBehavior"-->
                <endpoint address="" binding="webHttpBinding" behaviorConfiguration="webBehavior" contract="WindowsFormsApplication1.IService1">
                    <identity>
                        <dns value="localhost" />
                    </identity>
                </endpoint>
                <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
                <host>
                    <baseAddresses>
                        <add baseAddress="http://localhost:8733/" />
                    </baseAddresses>
                </host>
            </service>
        </services>
