Asp.net WCF未预期的文件结束错误

最近，我将我的项目

从.NET Framework 3.5升级到了4.0。

对于WCF，我正在使用自定义基本身份验证

在转换之前，一切正常。但是，在转换之后，我得到了“

意外的文件结束错误”

”。堆栈策略如下所示：

at System.Xml.EncodingStreamWrapper.ProcessBuffer(Byte[] buffer, Int32 offset, Int32 count, Encoding encoding)
   at System.Xml.XmlUTF8TextReader.SetInput(Byte[] buffer, Int32 offset, Int32 count, Encoding encoding, XmlDictionaryReaderQuotas quotas, OnXmlDictionaryReaderClose onClose)
   at System.Xml.XmlDictionaryReader.CreateTextReader(Byte[] buffer, Int32 offset, Int32 count, Encoding encoding, XmlDictionaryReaderQuotas quotas, OnXmlDictionaryReaderClose onClose)
   at System.ServiceModel.Channels.TextMessageEncoderFactory.TextMessageEncoder.WriteMessage(Message message, Int32 maxMessageSize, BufferManager bufferManager, Int32 messageOffset)
   at System.ServiceModel.Channels.WebMessageEncoderFactory.WebMessageEncoder.WriteMessage(Message message, Int32 maxMessageSize, BufferManager bufferManager, Int32 messageOffset)
   at System.ServiceModel.Channels.HttpOutput.SerializeBufferedMessage(Message message)
   at System.ServiceModel.Channels.HttpOutput.Send(TimeSpan timeout)
   at System.ServiceModel.Channels.HttpPipeline.EmptyHttpPipeline.SendReplyCore(Message message, TimeSpan timeout)
   at System.ServiceModel.Channels.HttpPipeline.EmptyHttpPipeline.SendReply(Message message, TimeSpan timeout)

   at System.ServiceModel.Channels.RequestContextBase.Reply(Message message)
   at ihv1Role.auth.BasicAuthenticationInterceptor.ProcessRequest(RequestContext& requestContext) in d:\src\auth\BasicAuthenticationInterceptor.cs:line 78

我遇到错误的类和方法如下所示：

   at System.Xml.XmlUTF8TextReader.SetInput(Byte[] buffer, Int32 offset, Int32 count, Encoding encoding, XmlDictionaryReaderQuotas quotas, OnXmlDictionaryReaderClose onClose)

如果标题中的用户名和密码有效，则整个服务运行良好。只有在请求未通过身份验证时，我才会收到此错误

有解决办法吗

谢谢

我自己解决了：

我在Web.config中添加了两次标记

删除它，现在我的服务很好
