vs2010 wcf 服务引用出错。

点击发现，可以发现服务，但是无法添加引用

Turn off ASP.NET compatibility mode in the web.config or add the AspNetCompatibilityRequirements attribute to the service type with RequirementsMode setting as 'Allowed' or 'Required'.

我使用的 vs.net 2010 

有两种解决办法：（在添加引用前，请先保证已经编译过。修改后，也需要再次编译。）

1、给服务添加上特性：

首先需要添加引用：

using System.ServiceModel.Activation

在添加特性：

  [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

 public class MyService : IMyService

2、修改web.configure文件

<serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true" />

将aspNetCompatibilityEnabled 修改为false

<system.serviceModel>
    <behaviors>
      <serviceBehaviors>       
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" />
                    <serviceDebug includeExceptionDetailInFaults="false" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
        <serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="false" />
    </system.serviceModel>
