JetBrains .NET Day Online ’23

How to recreate a classic 90s game using .NET and F# using the same techniques (an actual rasterized ray caster – it's all pixels!) to run natively in both the desktop and the browser.

In this session, you'll gain a deeper understanding of the available options in the observability space to become more effective in spying on your systems!

Join Denis in a fun coding session, where we will automate the process of instrumenting our codebase using Roslyn source generators. We will implement a well-known structural design pattern using incremental source generators and a sprinkle of OpenTelemetry.

Entity Framework Core is great for performing crud operations, but did you know you can also go beyond basic relational queries? Join Giorgi for a demo-rich session and learn about EF Core features that you will be able to apply right after the session.

Get started with microservice architecture! We'll look at The Tacky Tacos project, built with ASP.NET 6, and explore how the whole process fits together from a development point of view. Hopefully, you'll leave the session with the confidence to start your own microservices application development straight away!

This session will demonstrate how Avalonia UI enables you to create sleek, modern applications that run seamlessly across Windows, macOS, Linux, iOS, Android, and WebAssembly. Mike will also showcase how to revitalize legacy WPF applications and bring them to life on macOS and Linux using Avalonia XPF and JetBrains Rider!

Debug infrastructure implementation for .NET (Blazor) WebAssembly apps is challenging due to its unique execution environment. In this talk, we will dive deep into the hidden difficulties of debugger IDE frontend implementation for .NET WASM apps.

In this talk, you will see how features added to recent versions of C# can dramatically improve parsing and generation of JSON data compared with longer-established .NET JSON handling mechanisms. This talk will explore the tradeoff between maximizing performance and ease of use and will show you how to choose between the various options now available in modern .NET applications.

Learn what it takes to write the fastest Dictionary for .NET. Faster than the .NET Dictionary, faster than FrozenDictionary. You will learn how to use BenchmarkDotNet, dotTrace, and vTune to tune the most performance critical pieces of code and write optimized data structures in .NET. Whether you write C#, VB.NET, or F# you will learn how to extract the maximum performance from .NET.

This talk covers some xUnit tips and tricks: you'll learn how to make tests easier to write and more robust, as well as other helpful libraries that can be used in tandem with xUnit to unlock its full potential.
