“不是Found"在Silverlight 3中尝试通过WCF保存到SQL Server时出现错误

我正在尝试使用。net 3.5框架上的Silverlight 3将一些数据保存到SQL Server 2008数据库。

这里是关于这里发生的事情的概要。

当应用程序启动时，它调用WCF从DB下载一个包含行的List对象，这样所有可用的数据都在客户端，防止需要重复的客户机-服务器数据库调用。下载数据正常，并反馈数据下载成功。

用户在文本框中输入信息。当用户准备好了，他们点击"保存"，调用WCF保存这些数据，在一个加密的字符串可能不超过2kb的大小，连同一些整数和短字符串字段。

当他们点击Save时，会抛出以下异常:

远程服务器返回一个错误:NotFound.

我怎么也弄不明白发生了什么事。未保存数据

我试过的事:

• 在web中添加a绑定。配置(实际上导致第一次WCF调用失败并出现相同的错误)
• 用这个问题的内容添加一个crossdomainpolicy.xml文件
• 增加maxReceivedMessageSize和maxBufferSize的大小
• 将"includeExceptionDetailInFaults"设置为"True"(它没有提供任何有用的数据)

我已经无计可施了，需要在几天内完成这件事。如果解决方案是一条蛇，我敢肯定它会咬人……以下是我的文件内容:
