I have configured WCF via TCP. It works perfect under .NET, but under MONO
appears following exception
Dante.Tests.WcfTcp.AuthenticationProviderTests.AuthenticationShouldWorkWithViaWcfTcp
:
System.Runtime.Serialization.SerializationException : Type
'Dante.Contracts.Authentication.PinAuthenticationCommand' is
unexpected. The type should either be registered as a known type, or
DataContractResolver should be used.

My data class is:
[DataContract]
public class PinAuthenticationCommand : BaseAuthenticationCommand
{
[DataMember]
public string Pin { get; private set; }
public PinAuthenticationCommand(string pin)
{
Pin = pin;
}
public override AuthenticationStatus Execute()
{
if (string.IsNullOrEmpty(Pin))
{
return AuthenticationStatus.Rejected;
}
return AuthenticationStatus.Accepted;
}
}
}
and BaseAuthenticationCommand:
[DataContract]
public abstract class BaseAuthenticationCommand : IAuthenticationCommand
{
public virtual AuthenticationStatus Execute()
{
return AuthenticationStatus.Accepted;
}
}
I do not know how I should resolve it. I think it is not caused by Mono
missing feature. I tried add [KnownType(typeof(string))], but it does not
work - in my opinion it is absurdity. String is not third party class. I do
not have any other ideas. I will be grateful for your help.
