  • PowerShell

    PowerShell for every system!

    Project mention: Can't fetch a registered schema from Apollo Studio | reddit.com/r/graphql | 2023-02-08

    From the error, it sounds like you’re using Powershell, but the command you’re using is the Linux way of using online environments variables, though it’s a discussed feature. See the usable syntax on that thread.

  • ASP.NET Core

    ASP.NET Core is a cross-platform .NET framework for building modern cloud-based web applications on Windows, Mac, or Linux.

    Project mention: Need some conceptual help to start a project | reddit.com/r/nextjs | 2023-02-09

    I worked for 3 years as a programmer in an old ASP.NET webforms project so I know my way around a full stack project (DB, API, AUTH, CARTS, etc.). But I would like to learn the NextJS full stack framework / stack. I thought of a fun little (maybe not so little) project to start learning and use for portfolio.

    Project mention: That was quick, just got this from my mum in chch | reddit.com/r/newzealand | 2023-02-08

  • .NET Runtime

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

    Project mention: Update to the .NET Language Strategy | news.ycombinator.com | 2023-02-08

    .NET 6+ (fka .NET Core) is cross-platform.

    We've been developing on Windows and have been deploying exclusively to Linux since 2017, everything runs flawlessly. Only time where the deployed version was different was when the locale wasn't set in a Docker container.

    Developing on macOS has an issue with running HTTPS/2 and gRPC endpoints which should be resolved in .NET 8 [1].

    The notable part where .NET Core runtime is lacking vs legacy Windows .NET Framework is graphics, i.e. System.Drawing and all Desktop GUIs, otherwise it's a first class cross-platform runtime.

    [1] https://github.com/dotnet/runtime/issues/27727

  • MonoGame

    One framework for creating powerful cross-platform games.

    Project mention: About game engines | reddit.com/r/gamedev | 2023-01-18

    If you prefer a framework instead of an engine and editor they do exist, MonoGame is a popular one. I wouldn't recommend it unless you're doing it more as a hobby (in which case it's totally valid to do whatever suits you best), using engines with their editors and scripting languages is the industry standard.

  • MediatR

    Simple, unambitious mediator implementation in .NET

    Project mention: Nightclub Website | reddit.com/r/Blazor | 2023-01-23

    MediatR - for CQRS

  • ArchiSteamFarm

    Project mention: Ask HN: Those making $0/month or less on side projects – Show and tell | news.ycombinator.com | 2023-01-27

    ArchiSteamFarm: https://github.com/JustArchiNET/ArchiSteamFarm

    I've been developing ASF for last 8 years with very active attitude, 10k commits with over 7k commits made by me (98.6% of all excluding bots and automation). While I do offer various donation options, the program was always free and open-source, and the overall amount of hours I've put into this would probably make at least several years of senior-level salary by now.

    One of my finest creations that helped a lot of Steam users. The program was used approximately at 2.5 million of Steam accounts overall, having solid 30k downloads of each monthly release.

  • Chocolatey

    Chocolatey - the package manager for Windows

    Project mention: The newest feature in the Microsoft Store is more ads | reddit.com/r/pcgaming | 2023-02-04

    Or Chocolately. It even has a UI now!

  • BenchmarkDotNet

    Powerful .NET library for benchmarking

    Project mention: C#: Does Visual Studio 2022 offer a way to profile which function(s) are taking the most time during execution? | reddit.com/r/csharp | 2023-02-01

    It's common to use Benchmark DotNet for "micro benchmarking" i.e. timing small isolated bits of code like it's a unit test.

    Project mention: I'm considering giving up on MAUI Blazor Hybrid for creating an App | reddit.com/r/dotnetMAUI | 2023-02-03

  • ReactiveUI

    An advanced, composable, functional reactive model-view-viewmodel framework for all .NET platforms that is inspired by functional reactive programming.

    Project mention: I want to learn WPF and was told I should use a MVVM based framework any up to date suggestions? | reddit.com/r/csharp | 2023-01-05

    My favorite framework is Reactive UI but it's a bit more advanced than most MVVM frameworks since it uses Reactive Programming. You can still try its most basic features, though.
