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.

- Discriminated Unions: Essa feature faz falta no CSharp

DevDocs
Certain parts of Microsoft Learn are permissive, for example the .NET BCL documentation is Creative Commons Attribution: https://github.com/dotnet/dotnet-api-docs as is ASP.NET Core: https://github.com/dotnet/AspNetCore.Docs (a good hint if documentation is permissively licensed and on GitHub is if there's an edit button at the top.)
The C# language specification is unfortunately a bit fuzzier: https://github.com/dotnet/csharplang/discussions/4855
The updated unified C# language specification is CC, but it's still catching up to modern C#: https://github.com/dotnet/csharpstandard

The golden age of Kotlin and its uncertain future
No OP, but for example you still see the C# folks still struggling to add discriminated unions to the language because of complex interactions due to its too many features[1]. Virtual threads are easier to use than async/await is another example.

.NET 8 – .NET Blog
Hi there. I'm the language designer who created the 'Collection Expression' design/specification: https://github.com/dotnet/csharplang/issues/5354
You can see the entire history of the proposal there. To answer you specific question, we went with `..` because that's what the language already uses for the complimentary 'pattern matching deconstruction' form for collection patterns.
In other words, you can already say this today:
if (x is [var start, .. var middle, .. var end]) { ... }

What's new in C# 12: overview
Great improvements.
There is PolySharp project that enables you to use most of C#11 features in legacy .NET Framework: https://github.com/Sergio0694/PolySharp - Seems that C#12 features are planned to be implemented: https://github.com/Sergio0694/PolySharp/issues/78
I'm using PolySharp where I'm stuck with .NET Framework 4.6 and I don't have any issues.
Hope one day I'd see concise syntax for catch and/or try expressions: https://github.com/dotnet/csharplang/discussions/2734 - but there is a lot of resistance.
You must specify concrete type.
There was a plan to have "natural type" so "var list = [1,2,3]" would be of type "List" but it was postponed to C# 13 (https://github.com/dotnet/csharplang/issues/5354#issuecommen...)

Robust Design through Value Objects in C#
While C# currently lacks direct support for this kind of functionality, there's a glimmer of hope with an active proposal under discussion that aims to bring this feature to the language. This potential addition promises a future where C# can natively offer similar robust type narrowing.
-
The combined power of F# and C#
Given few people anticipated ValueTuple and C# adding a more direct tuple syntax, I feel like it is only a matter of time before C# adds discriminated unions.
(There are multiple proposals tracking the idea. This seems the most comprehensive and "central": https://github.com/dotnet/csharplang/issues/7016)

Interceptors (new C# metaprogramming feature) to fuel DapperAOT development
https://github.com/dotnet/csharplang/issues/7009
[Proposal]: Interceptors #7009
> An interceptor is a method which can declaratively substitute a call to itself instead of a call to an interceptable method at compile time. This substitution occurs by having the interceptor declare the source locations of the calls that it intercepts. This provides a limited facility to change the semantics of existing code by adding new code to a compilation (e.g. in a source generator).

Java 23: The New Features Are Officially Announced
If you care about portable SIMD and performance, you may want to save yourself trouble and skip to C# instead, it also has an extensive guide to using it: https://github.com/dotnet/runtime/blob/69110bfdcf5590db1d32c...
CoreLib and many new libraries are using it heavily to match performance of manually intensified C++ code.

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?
What are some alternatives?
