测试发布到虚拟目录中时发生的报错现象，由于不支持asp.net兼容性而导致服务无法激活启用。
具体错误信息如下：

可通过下面的配置（位于应用程序的 Web.config 文件中）在应用程序级别上启用 WCF 的 ASP.NET 兼容模式：
<system.serviceModel><serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> </system.serviceModel>
如果没有指定，则此值默认为“true”。若将此值设置为“false”，则指示在应用程序中运行的所有 WCF 服务将不在 ASP.NET 兼容模式中运行。
由于 ASP.NET 兼容模式暗含的请求处理语义与 WCF 默认值完全不同，因此单独的服务实现能够控制其是否在已启用 ASP.NET 兼容模式的应用程序内运行。服务可以使用AspNetCompatibilityRequirementsAttribute来指示其是否支持 ASP.NET 兼容模式。此特性的默认值为Allowed。
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
