In this tutorial we'll see how you can call Unary methods. We'll be using the RouteGuide example service that is part of the gRPC repository. Shown below is the *.proto definition of the service

As you can see above, ListFeature is a Server Streaming method. It accepts a request of type Feature and returns a stream of type Feature. Before we can call this method, we'll need to first discover the service. For that, please have a look at the Getting Started. Once the service is discovered and the client is generated and compiled you'll see the following
