注意：

在客户端添加Web引用时为避免额外的布尔值参数被使用，确保代理客户端强制执行时使用的RPC风格的编码，这是SOAP 1.1规范的一部分。

3.IIS 创建文件CalculatorService.svc

1 <%@ServiceHost Service="Services.CalculatorService"%>

4.IIS 寄宿服务配置，基于basicHttpBinding绑定 Web.config

 1 <?xml version="1.0"?>
 2 <configuration>
 3   <system.serviceModel>
 4     <behaviors>
 5       <serviceBehaviors>
 6         <behavior name="CalculatorBehavior">
 7           <serviceMetadata httpGetEnabled="true"/>
 8         </behavior>
 9       </serviceBehaviors>
10     </behaviors>
11     <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
12     <services>
13       <service behaviorConfiguration="CalculatorBehavior" name="Services.CalculatorService">
14         <endpoint address="" binding="basicHttpBinding" bindingConfiguration=""
15           contract="Contracts.ICalculator" />
16         <host>
17           <baseAddresses>
18             <add baseAddress="http://192.168.1.2:8080/CalculatorService.svc" />
19           </baseAddresses>
20         </host>
21       </service>
22     </services>
23   </system.serviceModel>
24   <system.web>
25     <compilation debug="true"/>
26   </system.web>
27 </configuration>

注意:为了保证 soap:address location 和wsdl:import location 显示和url里面的ip或者域名是一致请使用：<serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> ,multipleSiteBindingsEnabled 是.net framework 4里面支持的特性，如果版本低于4，例如3.5 那么就要根据IIS binding来设置baseAddress.

5.Main.axml 视图
