Microservices Communication in .NET Using gRPC

By: Fiodar Sazanavets

Overview of this book

Explore gRPC's capabilities for faster communication between your microservices using the HTTP/2 protocol in this practical guide that shows you how to implement gRPC on the .NET platform. gRPC is one of the most efficient protocols for communication between microservices that is also relatively easy to implement. However, its official documentation is often fragmented and.NET developers might find it difficult to recognize the best way to map between C# data types and fields in gRPC messages. This book will address these concerns and much more. Starting with the fundamentals of gRPC, you'll discover how to use it inside .NET apps. You’ll explore best practices for performance and focus on scaling a gRPC app. Once you're familiar with the inner workings of the different call types that gRPC supports, you'll advance to learning how to secure your gRPC endpoints by applying authentication and authorization. With detailed explanations, this gRPC .NET book will show you how the Protobuf protocol allows you to send messages efficiently by including only the necessary data. You'll never get confused again while translating between C# data types and the ones available in Protobuf. By the end of the book, you’ll have gained practical gRPC knowledge and be able to use it in .NET apps to enable direct communication between microservices.

Chapter 1, Creating a Basic gRPC Application on ASP.NET Core

  1. B. "You cannot have a Protobuf message definition without any fields" is an incorrect statement. You can have empty message definitions in Protobuf.
  2. A. ASP.NET Core is a cross-platform framework that works on Windows, Linux, and macOS, so gRPC can be implemented on them.
  3. C. You need to register each proto file by adding a Proto element to your project file. Then, you can specify the GrpcServices attribute inside it, which can be set to Server, Client, or Both. It's set to Both by default, so if you don't specify this attribute, both client and the server code will be generated. If you specify Server, only the server code will be generated. So, either Both or Server is a valid option for generating server code.
  4. C. To get gRPC to work inside an ASP.NET Core server app, you need to add all the required references to the project. Then, for each gRPC service definition, you need to create a...
