Question

我收到以下错误：“字典中没有给定的密钥。”

代码只是尝试创建代理客户端连接：

FileService.FileServiceClient svc = new CCS.FileService.FileServiceClient();

堆栈追踪：

我有一个Silverlight 3应用程序，我正在Web应用程序上添加WCF服务。有人知道解决这个问题的方法吗？看起来它很难获得绑定信息。

Answer 1

听起来像this is an issue with the Visual Studio加载错误的Silverlight 2文件而不是Silverlight 3文件：

要解决此问题，请卸载Silverlight 2 SDK，更新服务参考，然后重建Silverlight应用程序。

如果您希望Silverlight 2和Silverlight 3应用程序都可以使用您的服务，则可以将绑定更改回basicHttpBinding。为此，请编辑包含该服务的Web项目的web.config文件。然后更新服务引用并重建Silverlight应用程序。
