在 DevForce Config 中关闭 GZIP

Question

我有一个 Silverlight 5 应用程序部署在 IIS 7 中，使用数据源扩展连接到多个数据库。我们一直在经历“GZIP 流中的错误 CRC32”异常，因此我们决定听取建议，将 GZIP 绑定替换为二进制消息绑定并使用 IIS 压缩，这里给出了： Bad CRC32 in GZIP stream

但我的 web.config 中一定遗漏了一些东西。当我用 binaryMessageEncoding 替换 gzipMessageEncoding 节点时，我开始得到：

Cannot process the message because the content type 'application/x-gzip' was not the expected type 'application/soap+msbin1'.

当我的应用程序尝试与 EntityService.svc/sl 通信时。

这是我的 web.config，它基于 http://drc.ideablade.com/devforce-2012/bin/view/Documentation/code-sample-configuration-files 的 IIS 相关文件 中的示例 web.config。

我做错了什么？

客户端和服务器端的 WCF 绑定信息需要相同，因此您还需要在 Silverlight 客户端上添加或更改 ServiceReferences.ClientConfig 信息。 http://drc.ideablade.com/devforce-2012/bin/view/Documentation/code-sample-custom-client-servicemodel 有一个示例。
