Apps and Services with .NET 7

By: Mark J. Price

Overview of this book

Apps and Services with .NET 7 is for .NET 6 and .NET 7 developers who want to kick their C# and .NET understanding up a gear by learning the practical skills and knowledge they need to build real-world applications and services. It covers specialized libraries that will help you monitor and improve performance, secure your data and applications, and internationalize your code and apps. With chapters that put a variety of technologies into practice, including Web API, OData, gRPC, GraphQL, SignalR, and Azure Functions, this book will give you a broader scope of knowledge than other books that often focus on only a handful of .NET technologies. It covers the latest developments, libraries, and technologies that will help keep you up to date. You’ll also leverage .NET MAUI to develop mobile apps for iOS and Android as well as desktop apps for Windows and macOS.

Building Efficient Microservices Using gRPC

In this chapter, you will be introduced to gRPC, which enables a developer to build highly efficient services across most platforms. However, web browsers do not have full support for programmatic access to all features of HTTP/2, which is required by gRPC. This makes gRPC most useful for implementing intermediate tier-to-tier services and microservices because they must perform a lot of communication between multiple microservices to achieve a complete task.

Improving the efficiency of that communication is vital to success for the scalability and performance of microservices. A monolithic, two-tier, client-to-service style service could get away with being less efficient because there is only one layer of communication. The more tiers and therefore the more layers of communication there are between microservices, the more important efficient communication between those layers becomes, as shown in Figure 12.1:
