System.ServiceModel.CommunicationException was unhandled
Message="An error occurred while making the HTTP request to http://localhost:2122/Service1.svc. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server."

为什么要尝试跨web服务边界传输150MB？这种设计几乎肯定会导致服务端点上的可用性问题
更好的设计是将文件写入磁盘的某个位置，然后向服务发送命令消息以获取文件 为什么要尝试跨web服务边界传输150MB？这种设计几乎肯定会导致服务端点上的可用性问题
