我有一个 WCF 服务，可以根据输入参数返回大量数据。
该服务作为 ServiceHost 可执行文件在我的机器上运行，我现在正在使用 WCF 测试客户端进行测试。
这是我的主机配置:

这是我得到的错误:

Inner Exception:

当返回的数据多于一定数量的记录时会发生错误。使用较少的数据，一切都按预期工作。
关于如何解决这个问题有什么建议吗？
最佳答案
这一切都是由愚蠢的数据问题引起的。 错误信息是绝对没有用的。启用跟踪允许查看实际异常。 谢谢你，EkoostikMartin!
关于c# - WCF 错误 "The socket connection has been disposed"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11162190/
