.NET 8 favourites speed-run, with Ryan Rowston Let's race into the next generation of .NET with a speed-run through a few of my favourite new features is .NET 8. Blazor United, with John Merchant Not a soccer/football team, it's the latest iteration of tooling for writing web apps in .NET What's new in C# 12, with David Gardiner Find out about the 8 new language features that shipped with C# 12!

In 1971, three students from Minnesota thought they could liven up a history lecture by creating a computer game for the students to play, and after several days of work in HP Time Share BASIC, they came up with what turned out to be a significant milestone in the history of computer games - Oregon Trail. Oregon Trail is often regarded as one of the first great computer games, as well as being the originator of a franchise that is still running to this day. It was effectively also one of the first instances of both Shareware and a Commercial home release (depending on the version). My interest though, isn't just in historical computer games, it's also .NET and Functional Programming. I want to use this as a worked example of one of my passions - Functional Programming in C#! The challenge I've set myself is to redevelop Oregon Trail into C# using the following restrictions: Near 100% unit test coverage No variables can change state once set No statements (for, foreach, if, where, etc.) unless there literally is no way of avoiding them I'll also be demonstrating a few of the tricks Functional Programming can offer, like Higher-order functions, functional flows with simple Monads and Tail Recursion. There should also be a bit of retro computing fun, while we're at it. Links: Functional Programming with C# (O'Reilly Media) Simon on LinkedIn Simon on Twitter Simon's website

We have a challenge: Modern day administrators want to keep a tight rein on who can perform different actions in their systems. Join us and learn how we've evolved our authorisation patterns to grant highly granular permissions to different users, while maintaining developer-friendly patterns in code. In this talk I'll explain how we've approached this challenge, including: How we've encoded discreet permission levels as bits in a 64-bit integer using a .NET flags enum. How we've used an extended Authorize attribute to allow for developer to add authorisation in one line to API controllers/endpoints. How we've enabled dynamic policy generation to account for the potentially quintillions of unique permission combinations that this enables. Links: Ryan on LinkedIn

Have you ever loaded the official ChatGPT web application, entered a prompt and wondered: "How did they build that? How did they stream the response to the browser? And most importantly, how could I build it myself, using only C# and .NET"? Then this talk is for you! Especially if you are also interested in learning how leverage the new Azure OpenAI Service offering from Microsoft Azure! This talk also features GraphQL, using the HotChocolate server and StrawberryShake client libraries. Links: John's website John on Twitter John on LinkedIn

Come and learn how 'DevPulse', a cloud native .NET application for delivering interactive polls at AWS community expo booths was taken from ideation into production. In this session we will learn how .NET was used to build a cross platform application, delivering messages to an AWS IOT backend, how that backend then aggregated and stored these messages before sending on to a real-time dashboard showing the results. We'll also see what best practices you can use when approaching your next .NET application to run on native AWS services and what IAC and automation tools can be used to make updates and new features seamless. You might event learn a bit a bit about .NET MAUI, AWS Lambda, Amazon DynamoDB, AWS AppSync and Blazor Web Assembly too 😊 Links: https://dev.to/deekob Derek on Twitter Derek on LinkedIn

In this presentation, we will explore why gRPC is a technology worth considering for API service development in .NET. We will discuss the benefits of gRPC over RESTful APIs and provide an overview of the basics of creating a gRPC service project. We will also cover advanced topics, including server-side streaming, bi-directional streaming, authentication, and the use of interceptors. Additionally, we will demonstrate how to add a C# client project, a Python client, and a web client. Finally, we will discuss how to manage changes and conduct mock testing with gRPC. This presentation will provide you with enough information to make informed decisions about whether gRPC is the right choice for your next API project.

Hot Reload (and Edit and Continue) are reasonably amazing technologies allowing you to apply code changes on the fly, without stopping your application, or seemingly even recompiling it. Whilst a Hot Reload demo is all well and good (and I'm happy to provide one if you like), I personally find it much more interesting to talk about how it works under the hood, why some things don't work, what things might work in future, etc. This session will be a dive into the details of .NET DLLs, how they work, how Roslyn compiles deltas for them, and how the runtime applies them. All of that wonderful information you've always wanted to know, but were too afraid to ask! You'll learn absolutely nothing about JavaScript, microservices, or anything else your company actually uses, but at least you'll have a better understanding of what's in a .NET DLL, and a better idea of ILSpy is showing you next time you run it.

Whether it be MAUI, WPF, WinUI, Xamarin.Forms, UWP, Uno Platform, Avalonia, or any other technology that defines UIs with XAML, there are some common complaints about working with XAML files that have been around as long as XAML has. It can be hard to write, understand, maintain and modify. But, it doesn't have to be this way. The solution isn't abandoning XAML entirely, adopting a new framework, or using a different pattern. The solution is treating XAML like a "real programming language." By comparing it with how we write and work with C# and other files we compile into our applications, let me show you what we've been doing wrong, how we can do things differently, how it makes things better, and give you strategies for improving existing codebases. Or, you can tell me why I'm wrong, and that it's still appropriate that the XAML files created today look like the ones created 15+ years ago.. Links: Matt's blog Matt on Twitter

You've been bashing your head against a wall for 5 hours trying to figure out what went wrong. Suddenly you remember what you were thinking when you wrote this code 2 years ago. "But an if statement would be so easy here," you had said. "Nobody will look at this anyway," you had said. Past you was a real jerk, weren't they?!
