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.

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.

.NET web developer takes a job as a .NET desktop developer
You can go one step further and add https://github.com/Sergio0694/PolySharp to your project and you can use new C# 8+ features that don't require the new runtime (like file scoped namesapces, nullable annotations etc).

[Question] HttpClient does not recover from error
Is there a reason you're trying to reinvent PolySharp?
-
Do you prefer working with Java or C# legacy code?
You can still use C# 11 (with PolySharp), and you can still get a huge amount of new APIs via the various packages on NuGet that target .NET Standard 2.0. Plus you just get the usual .NET type system and BCL, which are still very good even if when using a framework from a few years ago.

Multi-targeted library, with a recent Language Version
Or the PolySharp NuGet package, which uses source generators to polyfill the language features you're actually using.

What's the biggest difference between C# and Java developers?
Well using PolySharp, of course! 😄

How to use C# 11 features in .NET 6 or older versions (even .NET Framework 2.0)
⚠️ Because PolySharp uses source generators, it doesn't work with the package.config file as stated in this issue. The issue says we need to use the SDK style .csproj, but just changing from package.config to Package Reference worked for me.

Playing with C# 12 & .NET 8
Some features like records and range require additional boilerplate classes to be added to become usable. You can DIY that or use PolySharp. Some features like static abstract members, default interface methods, etc require runtime support and can't be used.

The search for easier safe systems programming
Not exactly related to conversation but given that you mentioned (discriminated) unions, here are notes on recent design work:

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.

When static types make your code shorter
For example, C# had a research fork called Spec# that had compile-time support for contracts, with keywords such as requires (for arguments) and ensures (for return values), all the way back in 2004. While still being discussed, it doesn't seem to be shipping any time soon.

.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
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)

Should i quit Django and move to asp.net
I always liked list abbreviations in python, but I absolutely love Linq. I believe there is a feature proposal for C# 12, which makes collection initialization better imo.
