错误信息：

无法激活服务，因为它不支持 ASP.NET 兼容性。已为此应用程序启用了 ASP.NET 兼容性。请在 web.config 中关闭 ASP.NET 兼容性模式，或将 AspNetCompatibilityRequirements 特性添加到服务类型且同时将 RequirementsMode 设置为“Allowed”或“Required”。 
说明: 执行当前 Web 请求期间，出现未经处理的异常。请检查堆栈跟踪信息，以了解有关该错误以及代码中导致错误的出处的详细信息。

解决方案：

1、修改相应服务.svc.cs，在类上添加以下标识

using System.ServiceModel.Activation ;
[AspNetCompatibilityRequirements (RequirementsMode=AspNetCompatibilityRequirementsMode.Required)]

据说：启用了AJAX的WCF服务是默认添加的

小注：

更详细的问题分析参考：

The service cannot be activated because it does not support ASP.NET compatibility. ASP.NET compatibility is enabled for this application. 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'.
