GitHub - Tyrrrz/PolyShim: Collection of polyfills for projects targeting older versions of .NET Collection of polyfills for projects targeting older versions of .NET - Tyrrrz/PolyShim

Also want to take an opportunity to shout out a project of mine that's always been in the shadows:

github.com/Tyrrrz/PolyS...

It provides polyfills for ~500 BCL APIs, allowing you to write modern C#/.NET code on targets as old as .NET Standard 1.0 and .NET Fx 3.5.

I use it in all my libraries ✨

I've decided to aggregate all utilities/extensions I use across different C# projects into a single source-only package. I'm surprised there were so many, but it totals 130 individual files.

Feel free to copy-paste what's useful to you.

It applies 😁

Keeping my employee's preferences in check

Wut

Glad at least somebody's excited

Yeah I used to use Rider for years but it's gotten too bloated and slow for my preference.

I keep having issues with Dev Kit where it just doesn't see some package references about 65% of the time. The integrated build command (and dotnet build) works, but half the project gets covered in squiggly lines. Restarting sometimes helps, sometimes doesn't. It's awful.

I really want to use VSCode for .NET development but Omnisharp/C# Dev Kit just fucking sucks. Is there a better plugin out there?

Isn't it cool/weird that you can use features like ValueTask<T> and IAsyncEnumerable<T> on a legacy .NET Framework version from 2010?

Where is the line between AI-assisted and vibe-coded?

No, just a serial terminal in a browser

It's wild that this is possible

Explore union types in C# 15 - .NET Blog C# 15 introduces union types — declare a closed set of case types with implicit conversions and exhaustive pattern matching. Try unions in preview today and see the broader exhaustiveness roadmap.

C# 15's Union design looks really good. It's been a while since a new feature didn't look clunky and out of place.

And it's easily polyfillable too

Single-file command-line apps got even easier with CliFx. No setup or `Main()` method required.

CliFx v3 has been released ✨

Now uses source generators instead of reflection.

Fun fact: the original benchmarks were taken 5 years ago

2 minutes into using Arch btw

Why did you not call it carterm?

New milestone: got my code broken by Windows Update on CI

Slow day, installed arch btw

Accidentally tapped my security key and ended up with a syntactically valid Rust type definition

Help, how do I charge my files back to full?

Of course, I hope the AI bubble finally bursts and that it becomes just another tool on the shelf instead of a marketing or sales gimmick.

The only thing more annoying than AI grifters are the individuals on the opposite end of the spectrum who will instigate a class war if they sniff out that a random boilerplate config file in your repo was not written by a human.
