Is it possible to use an interface type as parameter type in a WCF operation?

There's some interface:

public interface IMessage
{
    string Content;
    Person Sender;
}

public class Priv : IMessage
{
    public string Content { get; set; }
    public Person Sender { get; set; }
    private int whatever;
}

public class Publ : IMessage
{
    public string Content { get; set; }
    public Person Sender { get; set; }
    private DateTime something;
}

Is it possible to use in wcf service IMessage instance? Like void SomeMethod(IMessage toSend)?

Yes, that is possible. You have to tell the Service the list of expected implementations you will send by using the KnownTypes attribute
