Доброго времени суток. Я новичок в WCF. Написал приложение. Есть сервис и графическая оболочка к нему (реализовано через netNamedPipeBinding), а также клиенты (реализованы через netTcpBinding).
При развертывании в локальной сети возникает исключение:
System.ServiceModel.Security.SecurityNegotiationException, System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
Message:
A security requirement was not fulfilled during authentication. Required: Sign, negotiated: EncryptAndSign.
(это данные трассировки)

Короче мне нужно отключить безопасность.
Есть варианты?
