【问题描述】：
我有一个 WCF 服务（服务器），其方法的签名是
public void SetProfilePic(String pSession, Applicant pApplicant)
申请人拥有财产：
public byte[] Photo { get; set; }
我从客户端得到一张图像并调用 SetProfilePic。当图像很小时，大约 1cm X 1cm，它可以完美地工作，但是，当图像较大时，4cm X 3cm，我得到下面的错误
"The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '01:49:59.9779945'."
我在 app.config 文件中增加了 最大限制，但我仍然遇到同样的错误。我在 缓冲 模式下使用 NetTCPBinding。我也试过 MTOM。由于该项目仍处于初始开发阶段，因此客户端和服务当前都在同一台机器上运行。
我在服务器端和客户端都启用了消息记录和跟踪，但是日志中没有提供更多详细信息，这不是很有帮助。
请在下面找到客户端和服务器的 App.config 文件。
我对 WCF 的体验只有几个月。任何帮助表示赞赏。提前致谢。

【问题讨论】：
-
奇怪，配置看起来不错。我唯一提到的：在服务器端 endpointBehavior 并没有真正应用于服务，因为没有指定 behaviorConfiguration。
-
bindingConfiguration相同，为空。您应该将其设置为 NetTcpBinding。我也没有得到你使用哪种绑定。您已配置 basicHttpBinding，但服务使用 netTcpBinding
