Beyond the Basics: Advanced Web Apps with .NET 8

There’s a lot more to ASP.NET 8 than models, views and controllers. In this workshop, you’ll learn how to make the most of the advanced features of Microsoft’s flagship development platform, from powerful asynchronous programming patterns like channels and callbacks, to support for cutting-edge frontend technologies like Razor Components, Blazor, and SCSS. We’ll look at advanced testing strategies for ASP.NET applications, and how to build observability into your .NET apps using OpenTelemetry and ASP.NET Aspire.

We’ve all seen the “hello world” demos: models, views, controllers, a DbContext, maybe some minimal API endpoints. In this workshop, we’ll go beyond the basics and explore the full potential of C# 12, ASP .NET Core 8, EF Core, and the rich ecosystem of libraries and packages that’s available for building web apps with .NET in 2024.

The workshop is based around “Rockaway”, a .NET web app for selling concert tickets. Our favourite developer-themed rock bands, from Dev Leppard to Mott the Tuple, are going on tour around the world, and we're going to build the platform that'll sell tickets to all their shows. Along the way we’ll encounter dozens of real-world scenarios, from data modelling, to timezones and currencies, to responsive layouts and email delivery. We’ll use asynchronous patterns and channels to build lightning-fast web apps which stay responsive even under heavy load. We’ll look at how to extend the built-in Bootstrap libraries with Blazor and Razor Components to create beautiful, responsive frontend layouts that work seamlessly with ASP.NET, and we’ll see how to test our applications at every level, from low-level isolation testing, to end-to-end integration tests which exercise the entire HTTP pipeline.

What You’ll Learn:

  • Principles of web application architecture: areas, services, components and dependencies
  • Testing ASP.NET Applications: WebApplicationFactory, Shouldly, AngleSharp
  • Deploying web apps using Azure and GitHub Actions
  • Observability with OpenTelemetry and .NET Aspire
  • Interactive frontends with Blazor and Razor Components
  • Advanced EF Core: mapping conventions and custom types
  • Testing database code using EF Core and Sqlite
  • Customising Bootstrap using SASS
  • Globalisation: dates, times and currencies
  • Async processing with threads and channels

This is a hands-on, interactive workshop: we’ll be sharing code throughout using GitHub and VS LiveShare, you’ll go home with a fully working copy of the sample application, and all the workshop code is published under the MIT license so you can use it for whatever you like. Application code is all built on .NET 8 using C# 12, so we can use new C# language features like primary constructors and collection expressions. You’ll also get to learn about many of my favourite developer tools like zoxide, oh-my-posh, MailTrap, Papercut, Postman, and ngrok: they’re not specific to .NET, but they do make building and testing .NET applications a lot easier.
