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.

Partial views

We already covered partial views in Chapter 8, API Controllers. Although they are a very interesting mechanism for reusing content, they historically have a problem—they could not be reused across assemblies. There has always been a way around this; the idea is to mark the view's .cshtml file as an embedded resource:

Then, we just need to use a file provider that knows how to retrieve the file contents from assembly-embedded resources. Add the Microsoft.Extensions.FileProviders.Embedded NuGet package for this example.

When registering the MVC services in ConfigureServices, we need to register another file provider, EmbeddedFileProvider, passing it to the assembly that contains the embedded resource:

.AddRazorOptions(options =>
var assembly = typeof(MyViewComponent).GetTypeInfo().Assembly;
var embeddedFileProvider = new EmbeddedFileProvider(assembly,
