(Incremental) source generators allow us to trade in a bit of compile time for better performance during runtime: instead of resorting to general-purpose types and methods, we may utilize auto-generated variants optimized specifically for our user code. With these at our fingertips, we can facilitate high-performance scenarios by, for example, using a Reflection-free source. If nothing else, this Roslyn-based metaprogramming relieves authors of writing repetitive patterns over and over again.

While source generators (compatible with the .NET 5 SDK) potentially cause a sluggish developer experience in huge projects and solutions, the programming model of incremental generators (added to the .NET 6 SDK) mitigates that risk. Come join me in a live coding session and witness the (test-driven) implementation of a fully operational incremental source generator. We will unveil (most of) the intricacies and benefits of incremental source generation along the way.

Remote pairing is a fabulous combination of highly engaging remote development with high people engagement and collaboration. In this live demo, we will take you through a variety of pairing tools and talk about the challenges and successes of remote pairing in each one.

Pairing solves many of the issues inherent in solo development. These include siloed development, lack of domain knowledge, poor mentoring, and insufficient upfront design. Pairing adds collaboration, knowledge sharing, real-time code review, and improved design.

We are going to role-play various dysfunctions with commonly used pairing tools, as well as present our favorite tools and better ways of working.

Whether you are new to pairing or a long-time fan, we have tons of suggestions for how to make the most of remote pairing.

Even if they're not our main focus, many of us regularly create console applications in .NET, be it to test some features, run some benchmarks, or automate some tasks. In all these use cases, we get the job done, but since it’s not the main focus of our day-to-day job, things end up a bit hacky and not as easy to use as they could be. What if I told you we can have our cake and eat it too? In other words, we can create these console applications to help us, but make them more user-friendly without too much hassle.

That's exactly where Spectre.Console comes in. It’s an open source library that helps us create beautiful console applications, from parsing command-line arguments, prompting the user for information, providing progress reports, and much more!

Building distributed applications is not an easy thing to do. Breaking down your application into a collection of focused services comes with a completely different set of challenges. This is where DAPR can help us out. It provides a runtime and a collection of building blocks that can be used with any language or on any cloud. In this session, we’ll dive into DAPR, discuss the various building blocks it supports, and see some demos of how you can make use of it in your .NET applications.

As a practical learner, I've found that performance optimizations are my biggest challenge and that I've learned the most helpful tricks from them, mostly by trial and error. It turns out the Azure .NET SDK is a perfect “playground” for learning those tricks – it's maintained by people who care and give feedback.

Over the past few years, I've contributed over fifty pull requests to the Azure .NET SDK. In this session, I'll walk you through the performance improvements I made and help you develop your own “superpowers” – spotting and avoiding closure allocations, finding opportunities for memory pooling, and more.

.NET has a long history on AWS. It has been supported for more than 11 years. The AWS SDK for .NET was the first-ever AWS SDK released.

When it comes to building cloud native applications with .NET, you can expect to use the full breadth and depth of AWS services to build modern applications.

In this session, I will introduce key services you can use with .NET to build cloud native applications. Then I will discuss the AWS Toolkit for Rider which brings AWS services into our favorite IDE. Finally I will run a live demo of how to quickly bootstrap a cloud native application leveraging AWS services with .NET.

No matter the industry, applications need to talk to each other. So, developers often build bridges – Application Programming Interfaces (APIs) – to allow one system to communicate with another.

Over time, different API architectural styles have been released. Each of them has its own characteristics, patterns of data exchange, pros, and cons. REST, GraphQL and gRPC are three main options when it comes to API development and implementation. In my session, I will cover what REST, GraphQL, and gRPC are, how APIs can be implemented using each of them, and give you a comparison between them.

Teams that are new to building and maintaining distributed systems with messaging are faced with challenges when it comes to investigating failure scenarios. With messages flowing through the system, it's hard to quickly identify where a failure originates from and why it's occurring. Without a call stack to guide you, we need other techniques to keep a good overview.

In this session, we'll navigate how modeling techniques, integration testing, and instrumentation with OpenTelemetry can help you create visibility for your entire distributed system.

Large online organizations like Netflix, Amazon, and LinkedIn have already been doing it for years: Chaos Engineering, i.e. injecting chaos into their production environments. And while it might sound scary (and it will be in the beginning), even you can apply some chaos to your applications. In this talk, I will demonstrate how to create chaos and how to apply resilience to work around it and create a more stable platform.

In this session we will look at the Chaos Monkey pizza shop, an event-driven, microservice oriented web application where you can order pizzas. The application will be running on Kubernetes, have a frontend, a GraphQL API, RabbitMQ, and a few .NET microservices. When everything is running smoothly, we will apply chaos on different components and try to resolve this chaos in different scenarios.

While trying to manage the application, it will become apparent that it is not only logging that is important but also traceability and metrics.

In this talk, I'll walk you through an amazing journey that started more than two years ago. We wanted to use artificial intelligence to predict the most fuel-efficient way to operate a vessel in the North and Baltic Seas, lowering carbon footprint. We were able to develop a robust solution with the right choice of cloud-based services combined with a subtle and effective .NET language. I'm going to show you how all this was possible.

Roman Provazník Principal Technical Lead .NET at CN Group CZ

Roman Provazník is a Principal Technical Lead .NET & Architect of CN Group CZ, OSS author, melomaniac, speaker, and a terrible drummer. With 20+ years of experience with software development, he tried many languages from Pascal and Prolog to Java and C#, but successfully forgot most of them.

As a big fan of the functional-first .NET language F#, he founded the Czech F# community which he loves to maintain and grow.

• Twitter: https://twitter.com/dzoukr

F# is a language that stretches across many boundaries (web, backend, domain modeling, etc.) and paradigms (functional, imperative, procedural, object-based) while being simple, succinct, and performant.

But there's more to it! In this session, we'll see why F# is also my favorite imperative, procedural programming language when it comes to performance.

We'll explore why chose F# as the language for our new Discrete-Rate Simulation engine, and how we achieved a >100x speedup over other simulation engines in our industry. All with just F# and .NET.

Need to run a task in the background in .NET 6? There are lots of scenarios for background tasks, ranging from a task that runs for a long time to perhaps an operation that needs to be retried multiple times if it fails, and many other scenarios in between. While there are lots of scenarios for background tasks, there are also lots of solutions to this problem – so many, in fact, that .NET developers can sometimes be unsure of which one to choose. Such solutions include IHostedServices, BackgroundServices, Worker Services, Hangfire, and more. In this talk, we'll break down all of these solutions, go over their pros and cons, and discuss when to choose one over the other. We’ll also take a deep dive to see how they all work under the hood.
