Top 10 C# help-wanted Projects

ASP.NET Core

1,633 34,396 9.9 C#

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

> 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”.

.NET Runtime

611 14,177 10.0 C#

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

Async/await is not a tight corner as showcased by a multitude of languages adopting the pattern: Rust, Python, JavaScript and Swift.
In fact, it is a clean abstraction where future progress is possible while retaining the convenience of its concurrency syntax and task composition.
Green threads experiment proved net negative in terms of benefit but its the follow-up work on modernizing the implementation detail was very successful: https://github.com/dotnet/runtime/issues/94620 / https://github.com/dotnet/runtimelab/blob/feature/async2-exp...
It also seems that common practices in Java indicate that properties are not a mistake as showcased by popularity of Lombok and dozens of other libraries to generate builders and property-like methods (or, worse, Java developers having to write them by hand).

WPF

51 6,827 9.7 C#

WPF is a .NET Core UI framework for building Windows desktop applications.

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.

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

MSBuild

19 5,139 6.9 C#

The Microsoft Build Engine (MSBuild) is the build platform for .NET and Visual Studio.
winforms

25 4,224 9.3 C#

Windows Forms is a .NET UI framework for building Windows desktop applications.

Project mention: Ask HN: Any way to write a simple desktop app anymore? | news.ycombinator.com | 2024-01-22

Windows Forms[0] is still alive and will never die, and very low overhead to start with, and works on new and shiny .NET 8.
If Linux or macOS, you can use AvaloniaUI[1] instead which is sufficiently advanced but assumes some prior knowledge.
