Question

In my business layer, i am using WCF service. WCF service instance can be passed in the constructor as well. Here are the constructors of my BL.

    private IWCFClient wcfClient;

    public MyBL()
        :this(new WCFClient())
    {

    }

    public MyBL(IWCFClient wcfClient)
    {
        serviceClient = wcfClient;
    }

because i am declaring my wcfClient as an interface, i dont get .Close() method there. I have to typecast it to close it as ((RealwCFClient)wcfClient).Close();

Is there a way i can close my client without typecasting it? Should i expose a Close method in my interface?

Answer 1

Cast your object to ICommunicationObject and then .Close() it.

Note that Close() can throw an exception, in this case catch it and do .Abort()
