To call service methods, we first need to create a *stub*.

+First we need to create a gRPC *channel* for our stub, specifying the server address and port we want to connect to and any special channel arguments - in our case we'll use the default `ChannelArguments` and no SSL:
```cpp
-grpc::CreateChannelDeprecated("localhost:50051", ChannelArguments());
+grpc::CreateChannel("localhost:50051", grpc::InsecureCredentials(), ChannelArguments());
```
Now we can use the channel to create our stub using the `NewStub` method provided in the `RouteGuide` class we generated from our .proto.
