Question

我正在使用EF创建WCF服务，并且具有带有数据批注的部分类以进行验证。但是从服务方法返回值时出现错误。如果我没有局部类而直接使用EF类，那么它会起作用。请帮忙。

错误：

远程主机强行关闭了现有连接

错误消息：

在收到HTTP响应时发生错误 http://localhost/Services/AppService.svc。这可能是由于服务端点绑定不使用HTTP协议。这也可能是由于 HTTP请求上下文被服务器中止（可能是由于服务关闭）。有关更多详细信息，请参阅服务器日志。

内部异常：

{System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host
