Question

我刚刚安装了.net framework 3.5 sp1后，我收到了以下错误。

:System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.InvalidOperationException: Type 'SL.CreateDocs' cannot be added to list of known types since another type 'SL.MyList' with the same data contract name 'http://schemas.datacontract.org/2004/07/SL.Object:DocList' is already present.

做.net框架3.5 sp1有任何问题。

我刚刚重新生成了wcf代理，新代理现在包含一些与故障相关的新部分。它解决了我的问题。

这是与框架3.5 sp1相关的问题
