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 web services using ASP.NET Core Minimal APIs

In earlier versions of ASP.NET Core, implementing even a simple web service required a lot of boilerplate code. For example, the ASP.NET Core Web API project template in ASP.NET Core 5 implements a simple weather service using four code files (controller, model, program, and startup class files), with a total 139 lines of code:

  • WeatherForecastController.cs has 39 lines of code
  • WeatherForecast.cs has 15 lines of code
  • Program.cs has 26 lines of code
  • Startup.cs has 59 lines of code

Compare that to a minimal Hello World web service implementation using Express.js, as shown in the following code:

const express = require('express')
const app = express()
const port = 3000
app.get('/', (req, res) => {
  res.send('Hello World!')
})
app.listen(port, () => {
  console.log('Example app listening on port ${port}')
})
