WCF un-expected end of file error - asp.net

Question

Recently I have upgraded my project from .NET Framework 3.5 to 4.0. For WCF I am using custom basic authentication.
Before conversion, all was working fine. However, after conversion I am getting "Unexpected end of file error". The stack strace is as below :
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.RequestContextBase.Reply(Message message)
at ihv1Role.auth.BasicAuthenticationInterceptor.ProcessRequest(RequestContext& requestContext) in d:\src\auth\BasicAuthenticationInterceptor.cs:line 78
The class and method in which I am getting error are as below :
p
ublic class BasicAuthenticationInterceptor : RequestInterceptor
{
MembershipProvider provider;
string realm;
public BasicAuthenticationInterceptor(MembershipProvider provider, string realm)
: base(false)
{
this.provider = provider;
this.realm = realm;
}
protected string Realm
{
get { return realm; }
}
protected MembershipProvider Provider
{
get { return provider; }
}
public override void ProcessRequest(ref RequestContext requestContext)
{
HttpRequestMessageProperty request = (HttpRequestMessageProperty)requestContext.RequestMessage.Properties[HttpRequestMessageProperty.Name];
string[] credentials = ExtractCredentials(requestContext.RequestMessage);
if (credentials.Length > 0 && AuthenticateUser(credentials[0], credentials[1], IsTestMode))
{
InitializeSecurityContext(requestContext.RequestMessage, credentials[0]);
}
else
{
Message reply = Message.CreateMessage(MessageVersion.None, null);
HttpResponseMessageProperty responseProperty = new HttpResponseMessageProperty() { StatusCode = HttpStatusCode.Unauthorized };
responseProperty.Headers.Add("WWW-Authenticate",
String.Format("Basic realm=\"{0}\"", Realm));
reply.Properties[HttpResponseMessageProperty.Name] = responseProperty;
requestContext.Reply(reply); // **Here I am getting error**
requestContext = null;
}
}
}
If the username and password in header are valid then whole service runs well. I am getting this error only if request is not authenticated.
Any solution?
Thanks

Resolved it my self :
I had added tag twice in Web.config.
Removed it and now my service is working fine.
