Question

我在我的开发箱上本地运行了一个WCF服务，我的测试检查了服务的一切情况。

通常，一切都很好，但有时（5％的时间），我得到错误

The requested service, 'net.tcp://csmattdev2:9000/Wcf/Service.svc' could not be activated. See the server's diagnostic trace logs for more information.

事件日志中的信息如下所示：

WebHost failed to process a request.
 Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/11404313
 Exception: System.ServiceModel.ServiceActivationException: The service '/Wcf/Service.svc' cannot be activated due to an exception during compilation.

要修复，唯一有效的方法是重置IIS，并重建comms项目。

任何想法可能是什么？

尝试从Web根目录中删除所有内容，但以下内容除外。

1）你用来暴露终点的.svc
2）.config文件
3）包含服务代码的bin文件

最重要的是，从Web根目录中删除所有Web应用程序内容
