Creating WCF ChannelFactory without an endpoint?

I read that we're not supposed to use using around WCF Client. So I found this awesome answer how to write elegant code around it.

It's not perfect, cause it's not async and it doesn't return any value, so I created my version (based on other answers):

    public static async Task<TReturn> UseServiceAsync<TChannel, TReturn>(Func<TChannel, Task<TReturn>> code)
    {
        ChannelFactory<TChannel> _channelFactory = new ChannelFactory<TChannel>("NetTcpBinding_IMyService");
        TChannel channel = _channelFactory.CreateChannel();
        bool success = false;
        try
        {
            TReturn result = await code(channel);
            ((IClientChannel)channel).Close();
            success = true;
            return result;
        }
        finally
        {
            if (!success)
            {
                ((IClientChannel)channel).Abort();
            }
        }
    }

It works great, but.. I don't want to specify my endpoint in the ChannelFactory. I provided contract interface already! It's totally enough to go to the config file and look for that endpoint. Why do I have to specify it explicitly?

BTW. In the mentioned answer, there is a link to the article.. and they do something like this:

public static ChannelFactory<T> _channelFactory = new ChannelFactory<T>("");

How is that supposed to work?? I don't know..

My question to you guys is: How to create ChannelFactory without passing endpoint name explicitly?

ChannelFactory<TChannel> derives from abstract class ChannelFactory. Create a custom derived class and use the InitializeEndpoint call to initialize the endpoint.

For example:

public class SomeChannelFactory : ChannelFactory
{
    public SomeChannelFactory()
    {
        InitializeEndpoint( new BasicHttpBinding() , new EndpointAddress( "http://localhost/service" ) );
    }

    protected override ServiceEndpoint CreateDescription()
    {
        return new ServiceEndpoint( new ContractDescription( nameof( SomeChannelFactory ) ) );
    }
}
