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.

Serving OData

OData is an open standard for querying data over the web. It allows us to expose metadata about a domain model and to query it using nothing more than HTTP verbs and the query string. It can be used, for example, to expose any data model as a REST API.

Previous versions of ASP.NET already supported it, and since version 2.0, it is also supported in ASP.NET Core through the Microsoft.AspNetCore.OData NuGet package.

For additional information about the OData spec, please check out

In the case of ASP.NET Core, OData allows us to query, through the URL, any collection that implements IQueryable<T> or IEnumerable<T>; in the first case, this means that the query will not be executed in memory, but it will be translated to the data source-specific dialect. In the case of an object-relational mapper, such as Entity Framework (EF) Core or NHibernate, this is SQL.
