Key benefits

Customize the default behavior of ASP.NET Core to get the most out of the framework

Enhance the app configuration, change the default dependency injection, and build your own tag helpers

Discover best practices for configuring ASP.NET Core, from user interface design to hosting it on platforms

Description

ASP.NET Core is the most powerful Microsoft web framework. Although it’s full of rich features, sometimes the default configurations can be a bottleneck and need to be customized to suit the nature and scale of your app. If you’re an intermediate-level .NET developer who wants to extend .NET Core to multiple use cases, it's important to customize these features so that the framework works for you effectively. Customizing ASP.NET Core 5.0 covers core features that can be customized for developing optimized apps. The customization techniques are also updated to work with the latest .NET 5 framework. You’ll learn essential concepts relating to optimizing the framework such as configuration, dependency injection, routing, action filters, and more. As you progress, you’ll be able to create custom solutions that meet the needs of your use case with ASP.NET Core. Later chapters will cover expert techniques and best practices for using the framework for your app development needs, from UI design to hosting. Finally, you’ll focus on the new endpoint routing in ASP.NET Core to build custom endpoints and add third-party endpoints to your web apps for processing requests faster. By the end of this application development book, you’ll have the skills you need to be able to customize ASP.NET Core to develop robust optimized apps.

This is not a book for beginners, the author assumes you already know at least the basics about ASP.NET Core and you're looking to, as the book name suggests, customize the default behavior.One thing that I like particularly is that each chapter is self-contained, by that, I mean that the author explains how to start a new project and implement the particular example from scratch, often, other authors use the same solution across the whole book, and reuse snippets from another chapter, if you're not following along and you want to test just something you might get into a situation where you can't implement the given example due to some part of the solution is missing, anyway, that won't happen if you try to implement any of this book's examples.Another thing is that the author doesn't assume his way is the best, and not only suggests you look for other ways to implement that solution but also refers the readers to blog posts and other resources so you can learn a different perspective and decide which solution is the best for your case.The author explains what's the scope for each chapter and tries to give some examples of use-cases where such customization might be used or important, such as, using a 3rd Party Dependency Injection Container, customizing HTTPS with Kestrel, creating custom ActionFilters, TagHelpers, etc...This book is what I classify as a "cookbook" and definitely one book to have at hand to use in the real world.

I really love this book. It has several real world approaches to improving code and writing better software systems; especially if you are a seasoned .Net developer who wants to brush up on enterprise coding practices. I would recommend this to anyone looking to add to their skill set in .Net while moving to .Net 5 platform.

I’d especially recommend this book as a developer’s 2nd book on ASP.NET Core once they have read through an “I’m starting from scratch” beginner book. The content in this book will build on that intro.Such a developer will find the following customizations covered by this book particularly useful: logging, configuration, dependency injection, writing middleware, model binding, ActionFilters, TagHelpers and Endpoint Routing. While some of those maybe covered in an intro book, it’s helpful having a 2nd resource on these topics as they from the backbone for how ASP.NET Core works.Many will find it nice that this book doesn’t spend a lot of time wading through theory, but rather gets you to usable code very quickly. And the book even covers a few more advanced topics like IHostedService , BackgroundService and hosting on NGINX or Apache on Linux..NET Core opens up so many new doors and this book will help you walk through them.

The title of the book got me interested. While there are lots of books teaching the .NET Core 3/5, a Productionzed Microservices has different requirements. I would not like to choose the .NET 5 Framework for a specific application/set of Microservices and then dive into the extensive documentation to learn how to meet these production environment requirements like configuring logging, telling the Microservice how to retrieve configuration, etc. Learning Curve and shortening the learning curve i.e. 160 pages is absolutely critical for me.On the configuration requirements alone, while .NET 5 does a commendable job that matches other popular Microservices frameworks like SpringBoot, there is hardly a one size fits all. Different companies may have different standards, central repositories, and other platforms where configuration is hosted. Besides, a production environment will need HTTPS, and learning how to do that with Kestrel in chapter 4 is a critical value addition. Running software in the background, writing custom middleware, customizing different formatters for different outputs, binding objects with different inputs, writing custom tag helper are great lessons. Finally, understanding the varieties of .NET Core 5.0 deployment models in chapter 12 and learning how to route requests in chapter 13 are the icing on the cake.The best part is its size total of 161 pages, teaching so many great things transforming a .NET Core developer from a laptop/desktop developer to a production-focused developer.Highly recommended, and I am using it for my teams as well!Thanks,Binit

The book, Customizing ASP.NET Core 5.0, deals with tweaking the knobs at various layers:- WebAPI- Razor Pages- MVC/SignalR/gRPC/Blazor/etc.- Routing- Middleware- Hostsuch customizing logging, dependency injection or writing custom middleware.Each chapter indicates what layer is that particular tweak related to and goes in-depth the pros and cons of the tweak.I enjoyed this comprehensive book and would have it as a handy companion during design and performance tuning sessions.
