Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Hello everyone, I made a Windows 10/11 Multitool app with Winforms. I'm just gonna share some screenshots.

How did you guys get your first C# job?
Started programming by writing some apps for Windows Phone later UWP during university. A few years ago I started collaborating a lot on GitHub to some Microsoft projects, like the Windows Community Toolkit. There I created a lot of new APIs and libraries, like all the new animation APIs and pipeline brush APIs, etc. I then also proposed adding some general .NET APIs to it, and that's how the MVVM Toolkit was born, along with other libraries which are now moved to the .NET Community Toolkit. Fast forward until about late 2020, and they pinged me saying the new Microsoft Store (which hadn't been announced yet back then) was using several of those new APIs I had written, so we started collaborating more so that I could add more functionality they needed. After that shipped, at some point there was a new opening to which I applied, and here I am in the Microsoft Store team and also leading the .NET Community Toolkit 🙂

Why is there a lack of cool repos?

Does anyone here have a long background with Java before switching/using C#? What caused you to switch and what do you miss about Java that C# doesn't have?
For instance, recently Chaochao opened a PR for the Windows Community Toolkit to open source the whole custom animation helpers he developed for the Store, which are used to implement the morphing animations you see when scrolling in a product page. You can see a GIF and the whole code here and in the linked PR.

Where is the source for Microsoft.Toolkit.MVVM?
Specifically I am looking for AsyncRelayCommand.cs. All documentation points to CommunityToolkit repo but I can not find it there. Link to source repo from the Nuget package also points to CommunityToolkit. I am not looking for samples.

Improve C# code performance with Span<T>
That's interesting. It will need some documentation and to finish the renaming at some point, e.g. Span2D is in https://github.com/CommunityToolkit/WindowsCommunityToolkit but as you say doesn't require Windows.

Why choose async/await over threads?
We might not be that far away already. There is this issue[1] on Github, where Microsoft and the community discuss some significant changes.
There is still a lot of questions unanswered, but initial tests look promising.

Redis License Changed
https://github.com/dotnet/dotnet exists for source build that stitches together SDK, Roslyn, runtime and other dependencies. A lot of them can be built and used individually, which is what contributors usually do. For example, you can clone and build https://github.com/dotnet/runtime and use the produced artifacts to execute .NET assemblies or build .NET binaries.

Garnet – A new remote cache-store from Microsoft Research
Thank you, I missed the [stack allocation](https://github.com/dotnet/runtime/blob/main/docs/design/core...) design doc stating it’s on the roadmap.
Appreciate the detail about the stack allocated bits in .NET.
Yeah, it kind of is. There are quite a few of experiments that are conducted to see if they show promise in the prototype form and then are taken further for proper integration if they do.
Unfortunately, object stack allocation was not one of them even though DOTNET_JitObjectStackAllocation configuration knob exists today, enabling it makes zero impact as it almost never kicks in. By the end of the experiment[0], it was concluded that before investing effort in this kind of feature becomes profitable given how a lot of C# code is written, there are many other lower hanging fruits.
To contrast this, in continuation to green threads experiment, a runtime handled tasks experiment[1] which moves async state machine handling from IL emitted by Roslyn to special-cased methods and then handling purely in runtime code has been a massive success and is now being worked on to be integrated in one of the future version of .NET (hopefully 10?)

The Mechanics of Silicon Valley Pump and Dump Schemes
The math of the above is really simple. Microsoft has 13,000 stars on their GitHub profile for their flagship product. SupaBase has 63,000 stars on their GitHub project for their flagship product. 27% of all software developers in the world are using .Net. SupaBase has 4.5 times as many likes as the .Net Core runtime, so they must be 4.5 times as large, right? 4.5 multiplied by 27% becomes 130%. Implying 130% of all software developers that exists on earth are using SupaBase (apparently!)

OpenD, a D language fork that is open to your contributions
> The amount of unsafe code used to implement C# vastly outweighs the amount in Rust's standard library.
According to bing.com chat, https://github.com/dotnet/runtime has 3.5M LOC, and https://github.com/rust-lang/rust has 6M LOC. The left panel of https://github.com/dotnet/runtime says 80% of the .NET runtime is written in C#.
This makes me wonder, do you happen to have a link for your “vastly outweighs” statement?

Ask HN: What's the fastest programming language with a large standard library?
Movemask keeps coming back. Rather than emulating it, it appears to be more efficient to separately handle IndexOfMatch, LastIndexOfMatch and GetMatchCount scenarios it is used for most of the time:
- https://github.com/dotnet/runtime/pull/94472/files#diff-5824... (it's closed for now but I'm hoping to get back to it at some point)
- https://github.com/jprochazk/tmi-rs/blob/ac3ce6aee8bbe038a98...
It can account for good 30% performance variance depending on the use case (on Apple's M-series cores).
.NET's standard library is very heavily vectorized, vectorization is considered in all scenarios where it is applicable, the compiler will also apply it to copies of known length and string comparisons fully eliding and unrolling Memmove and SequenceEqual calls.
The gives languages that run on top of .NET massive performance advantage in a variety of scenarios versus any other language - C++ and Rust stdlibs are far more conservatively vectorized because neither language has stable SIMD vector API and even then out of modularity constraints a lot of routines have to either rely on autovectorization which is fragile or manually vectorized with intrisics for each individual platform.
A short non-exhaustive list of examples is
- Shared SIMD helper for Aho-Corasick, Rabin-Karp and other text search algorithms https://github.com/dotnet/runtime/blob/main/src/libraries/Sy...
- Bloom filter https://github.com/dotnet/runtime/blob/main/src/libraries/Sy...
- Base64 encoding and decoding https://github.com/dotnet/runtime/blob/main/src/libraries/Sy...
- Element search (memchr and the like) https://github.com/dotnet/runtime/blob/main/src/libraries/Sy...
- UTF-8 transcoding https://github.com/dotnet/runtime/blob/main/src/libraries/Sy...
The above are examples of 1% code that ends up used by 99% of other codebase in one way or another. Regex engine, JSON serialization and parsing, substringing and etc. all use these.
Rust has had a stable SIMD vector API[1] for a long time. But, it's architecture specific. The portable API[2] isn't stable yet, but you probably can't use the portable API for some of the more exotic uses of SIMD anyway. Indeed, that's true in .NET's case too[3].
Rust does all this SIMD too. It just isn't in the standard library. But the regex crate does it. Indeed, this is where .NET got its SIMD approach for multiple substring search from in the first place[4]. ;-)
You're right that Rust's standard library is conservatively vectorized though[5]. The main thing blocking this isn't the lack of SIMD availability. It's more about how the standard library is internally structured, and the fact that things like substring search are not actually defined in `std` directly, but rather, in `core`. There are plans to fix this[6].
