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.

This chapter dealt with data coming from the user and data that, because of that, needs to be validated; otherwise, it would be possible to submit invalid information, even if improperly formatted. After reading through this chapter, you should be able to design a form to receive complex data structures as well as validate them.

For validation, you should probably stick to data annotations attributes and IValidatableObject implementations, if need be. These are used in a plethora of other .NET APIs and are pretty much the standard for validation.

It would be good to implement client-side validation and AJAX as it provides a much better user experience, but never forget to alsovalidate on the server side!

There is probably no need for custom model binders as the included ones seem to cover most cases.

Display and editor templates are very handy, so you should try to use them as it may reduce the code you need to add every time, especially...
