Simple WCF Proxy

Proxy.cs

public static class Proxy<T>
{
    private static readonly ChannelFactory<T> ChannelFactory = new ChannelFactory<T>("*");

    public static void Execute(Action<T> serviceAction)
    {
        var proxy = (IClientChannel) ChannelFactory.CreateChannel();
        var success = false;
        try
        {
            serviceAction((T) proxy);
            proxy.Close();
            success = true;
        }
        finally
        {
            if (!success)
            {
                proxy.Abort();
            }
        }
    }

    public static TResponse Execute<TResponse>(Func<T, TResponse> serviceAction)
    {
        var response = default(TResponse);
        Execute(new Action<T>(service => response = serviceAction(service)));
        return response;
    }
}

The most simple way of creating a WCF proxy I've seen so far.

Usage:

Proxy<IMyServiceContract>().MyOperation("Hello World");

Remarks

• The "*" is a wildcard by which the ChannelFactory will search for the endpoint with the correct contract.
• A ChannelFactory is created per contract type, as it is a static generic field. Creating a ChannelFactory is costly, so done only once per contract. Creating the channel is cheap, so done for each call.
