Modern Web Development with C# and .NET
It’s 2023. .NET is a free, open-source development framework that runs on everything from Raspberry Pis to cloud data centres, server-side rendering is cool again, and despite what you might have read on LinkedIn, AI is not about to take away all our jobs. In this two-day, workshop, you’ll learn how to design, deliver, and test state-of-the-art web applications that harness the power of the C# language and the ASP.NET Core platform. Alongside familiar patterns like model/view/controller and dependency injection, the latest versions of ASP.NET Core introduced a streamlined hosting model, a new set of conventions for routing requests within our applications, and a completely new architecture known as “minimal APIs” for building API endpoints and microservices.
.NET also supports a thriving ecosystem of open source projects and packages. Entity Framework Core provides first-class abstractions over relational databases like MS SQL Server and PostgreSQL. Libraries like NodaTime can simplify and streamline your application logic. Projects like xUnit, Moq, and Shouldly let you test your applications at whatever level makes sense - from low-level unit testing to end-to-end integration tests that test your app’s entire HTTP pipeline. And on the front-end, it’s never been easier to incorporate technologies like SASS, CSS grids, responsive layouts, and even libraries like MJML for sending HTML emails.

Target Audience and Prerequisites
This workshop is aimed at developers with some experience of the C# language, the .NET platform, and some basic web development. If you understand classes, inheritance, Console. WriteLine, and you know what the <select> tag in HTML does, then you should be just fine.
Attendees will need a computer running .NET 6 or .NET 7, Docker, and a code editor that supports .NET such as Microsoft Visual Studio 2022, JetBrains Rider, or Visual Studio Code.
