Building a gRPC service and client

Let’s see an example service and client for sending and receiving simple messages.

Building a Hello World gRPC service

We will start by building the gRPC service using one of the project templates provided as standard:

1. Use your preferred code editor to create a new project, as defined in the following list:
   • Project template: ASP.NET Core gRPC Service / grpc
   • Solution file and folder: Chapter13
   • Project file and folder: Northwind.Grpc.Service
   • Enable Docker: Cleared.
   • Do not use top-level statements: Cleared.
   • Enable native AOT publish: Selected.

   Good Practice: Make sure to select Enable native AOT publish. With .NET 8 and later, gRPC projects can be ahead-of-time (AOT) compiled for native platforms. This gives improved performance and a reduced start time, which is important for microservices that are frequently redeployed and spun up and down...
