C# 代码中的WCF protobuf网络端点

我想在我的代码中序列化wcf客户端，而不是使用app.config

主要问题是我不知道如何将protobuf支持从App.config移到代码中。 我需要这个原因是更充分的管理内部代码的变化，也考虑如果我更新服务引用，它将覆盖App.CONFIG，这是不好的。 我的例子是：

WSHttpBinding clientBinding = new WSHttpBinding();
clientBinding.Security.Mode = SecurityMode.None;
clientBinding.MaxReceivedMessageSize = 10000000;
const string _serverlink = "http://localhost:56142/SimpleService.svc";

using (TestClient client = new TestClient (clientBinding, new EndpointAddress(_serverlink )))
{ //do something }

App.config
