我收到ServiceModel.CommunicationException，说没有为我的绑定设置MaxMessageSize属性。问题是我的客户端和WCF服务分别在app.config和web.config文件中设置了此属性。我假设客户端中的服务引用没有使用配置中的设置，但我不确定为什么不是这种情况。
错误消息：
Web.config客户端app.Config：
System.ServiceModel.CommunicationException was unhandled
HResult=-2146233087
Message=The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

如您所见，我为＆＃34; DefaultBinding＆＃34;设置了MaxReceivedMessageSize，但错误消息仍然引用了最大邮件大小65536.
