c# - Identify on which Contract was a WCF service called

Is possible to know which contract has been called in a multiple contract service? In this, case, in the constructor.

The implementing class of the service is like this:

public class Service : IContract1, IContract2
{
    public Service()
    {
        //Identify if constructor was called from IContract1 or IContract2
    }
}

I think what you want to implement is a WCF Message Inspector. A MessageInspector is a "message filter" that can intercept and inspect the messages coming in or going out of the service layer infrastructure.

On the server, you would implement the IDispatchMessageInspector Interface.

Here is a pretty good example:
