  • Project mention: Asynchronous Programming in C# | news.ycombinator.com | 2024-04-30

    > Just .GetAwaiter().GetResult() it.

    That won’t work with various synchronization contexts, where doing this would cause a deadlock. There’s not much fun in trying to debug such issues.

    And now that various libraries only provide async api, or worse an non-async version wrapping the async one with . GetAwaiter().GetResult(), you’ll be in for a treat updating your dependencies.

    Async all the way is the answer, although various frameworks still don’t offer async hooks. Recently I ran into this for example trying to write an async validator in blazor, but that’s not possible and you have to work around it [1].

    C# 5 introduced async/await almost 12 years ago. And we’re still not “async all the way”.

  • Project mention: The search for easier safe systems programming | news.ycombinator.com | 2024-05-08

    WPF is not the best example of open source, as some components are still closed source. Though it only runs on Windows, a closed source operating system, so perhaps that is not so important.

    https://github.com/dotnet/wpf/issues/2554

    That said, there are cross platform, open source .NET UI frameworks out there, including one that is inspired by WPF:

  • .NET Runtime

    .NET is a cross-platform runtime for cloud, mobile, desktop, and IoT apps.

  • Project mention: Microsoft's $1M Vote of Confidence in Rust's Future | news.ycombinator.com | 2024-05-12

    When .NET (that is, what became CoreCLR runtime flavour) became open-sourced, it was done in such a way as not to cause issues for existing Mono, Xamarin and Unity code, and allow cleanly merging the first two into overarching .NET ecosystem.

    https://github.com/dotnet/runtime/blob/main/LICENSE.TXT

    https://github.com/dotnet/runtime/blob/main/PATENTS.TXT

    Given that MSFT never sued anyone for .NET or .NET-related matters, so far their reputation is clean in that area, unlike certain Java-related company.

  • OpenRA

  • Project mention: The Rise and Fall of the LAN Party | news.ycombinator.com | 2024-04-24

    Recently, my friends and I recreated our old LAN parties. Went up to a cabin in the woods, brought some cheap network switches, and had everyone install OpenRA (https://www.openra.net/, open red alert), and had a blast, even with everyone on laptops (mac/win). You can still do this in 2024 and it's worth it!

  • Polly

    Polly is a .NET resilience and transient-fault-handling library that allows developers to express policies such as Retry, Circuit Breaker, Timeout, Bulkhead Isolation, and Fallback in a fluent and thread-safe manner. From version 6.0.1, Polly targets .NET Standard 1.1 and 2.0+.

  • Project mention: The Retry Pattern and Retry Storm Anti-pattern | dev.to | 2024-01-15

    In our applications, we should wrap all requests to remote services in code that implements a retry policy that follows one of the strategies I listed earlier. If you are a .NET developer like myself, you may be familiar with the Polly library. Golang has a library called Retry, and there are numerous third-party libraries for Python and Java.

  • Project mention: How exactly does Unity integrate with IDEs - how does the editor build work? | /r/Unity3D | 2023-07-23

    In the video you basically install .NET 7.0 SDK with the deb packages from Microsoft repos AND mono deb packages from repos laid out in https://www.mono-project.com/ apart from Unity and VS Code. And then you configure VS Code so that it always uses Mono installed in the system (not Unity Editor's own instance???)

  • MonoGame

    One framework for creating powerful cross-platform games.

  • Project mention: The MonoGame Foundation launch | /r/monogame | 2023-11-15

    To highlight this shift, we are introducing a new website which is now fully automated with Github. The paint is still fresh, but we hope to expand it with more information about the MonoGame Foundation, like how it operates, and how to join it or contribute.

  • ArchiSteamFarm

    C# application with primary purpose of farming Steam cards from multiple accounts simultaneously.

  • Project mention: Is still safe to use steam idle? | /r/Steam | 2023-12-07

    Why should they? But be sure to use Open Source Projects like https://github.com/JustArchiNET/ArchiSteamFarm or https://github.com/JonasNilson/idle_master_extended so that no funny business happens due to your account due to shady idler programs. Idler programs simply mimic what you're doing and Steam doesn't care about you actually played the game or idled the time since Playtime is IR-reversible and the more you idle, the more you can't refund the game which suits them well.

  • QuestPDF

  • Gui.cs

    Cross Platform Terminal UI toolkit for .NET

  • Project mention: Ask HN: Interesting TUIs (text user interfaces), maybe forgotten ones? | news.ycombinator.com | 2024-05-06

    As someone who writes software for moderately boring business operations, I've been wondering making terminal-based apps with lots of keyboard shortcuts would lead to a more productive end user than writing a web app.

    I've been looking at https://github.com/gui-cs/Terminal.Gui but haven't tried it yet.
