What is the best workaround for the WCF client `using` block issue?

I like instantiating my WCF service clients within a using block as it\'s pretty much the standard way to use resources that implement IDisposable:

    I used Castle dynamic proxy to solve the Dispose() issue, and also implemented auto-refreshing the channel when it is in an unusable state. To use this you must create a new interface that inherits your service contract and IDisposable. The dynamic proxy implements this interface and wraps a WCF channel:

    Func createChannel = () =>
    ChannelFactory
        .CreateChannel(new NetTcpBinding(), new EndpointAddress(uri));
var factory = new WcfProxyFactory();
var proxy = factory.Create(createChannel);
proxy.HelloWorld();



    I like this since you can inject WCF services without consumers needing to worry about any details of WCF.  And there's no added cruft like the other solutions.
    


    Have a look at the code, it's actually pretty simple:
