Modern Web Development with ASP.NET Core 3 - Second Edition

By: Ricardo Peres

Overview of this book

ASP.NET has been the preferred choice of web developers for a long time. With ASP.NET Core 3, Microsoft has made internal changes to the framework along with introducing new additions that will change the way you approach web development. This second edition has been thoroughly updated to help you make the most of the latest features in the framework, right from gRPC and conventions to Blazor, which has a new chapter dedicated to it. You’ll begin with an overview of the essential topics, exploring the Model-View-Controller (MVC) pattern, various platforms, dependencies, and frameworks. Next, you’ll learn how to set up and configure the MVC environment, before delving into advanced routing options. As you advance, you’ll get to grips with controllers and actions to process requests, and later understand how to create HTML inputs for models. Moving on, you'll discover the essential aspects of syntax and processes when working with Razor. You'll also get up to speed with client-side development and explore the testing, logging, scalability, and security aspects of ASP.NET Core. Finally, you'll learn how to deploy ASP.NET Core to several environments, such as Azure, Amazon Web Services (AWS), and Docker. By the end of the book, you’ll be well versed in development in ASP.NET Core and will have a deep understanding of how to interact with the framework and work cross-platform.

Logging, Tracing, and Diagnostics

Logging, tracing, and metrics are essential features of any non-trivial application, for the following reasons:

  • Logging tells us what the system is doing, what it is about to do, the errors it encounters, and so on.
  • Tracing is about collecting transactional information about journeys and how they flow in a distributed system.
  • Metrics involves getting information in real time about what is happening and possibly producing alerts from it.

In this chapter, we will have a look at some of the options we have at hand, from the simplest to the most complex.

We will cover the following topics in this chapter:

  • Introducing the.NET Core Common Loggingframework
  • Writing custom logging middleware
  • Using tracing and diagnostics
  • Using performance (event) counters for obtaining metrics
  • Using...
