.NET 11 moves async/await into the runtime itself. Stack traces drop from 13 frames to 5, allocations cut by 42%, and you don't change a single line of code.

#dotnet #async #performance
Bonus question:
Can you set any integer on an enum? Like in your example, can you set Weekdays day = 42;
Does this work?
... Drumroll
..
..
.
Yes, you can do it, even though such an enum does not exist.
So, if you need to make sure, Enum.IsDefined is your friend. Or wait for Unions coming in Nov 🤟

"...just for once, Hollywood's had an attack of common sense..."
Apparently that's newsworthy now. Pay writers. Make something new. Nobody wants three-day-old leftovers.

That's going to sell jetbrains licenses! Let's hope and see 😀
One followup question: would it mean to be really cross-platform and cross VSCode clone? I mean, will R#Extension work on Mac, Linux and Winslop on any VSCode clone (or just on any clone where microslop doesn't allow the c#devkit? That would be the USP! Working debugger on any VSCode clone.
When the debugging really works and I can get rid of the c#/dev kit, I'll give it a try... Until then I'm fine.
This was a fantastic read! iev.ee/blog/resharp-how-we-buil...
In the end VSCode is not good to handle too many extensions and gets bloated by the minute and it's worse now with the deprecation of Azure Data Studio (I hate SSMS) but the VSCode extensions so far are not on the same level as ADS was but that's what I have to live with.
Then I disabled R# and I was back in business with all the other extensions I used frequently so I got rid of the R# extension for good and now I stick to Rider or VS if ReSharper functionality is needed or use the jetbrains cli tool for code formatting based on our team dotsettings file /2
It didn't play well with the c#/devkit. Debugging a solution wasn't working anymore and refactorings I was used to from Rider/R#4VS weren't there. Then VSCode ExtensionHost started to chrash all the time so nothing was working anymore. Extension bysect then concluded it was ReSharper or C#DevKit /1
I tried it when I first read the announcement weeks ago and as fast as it was installed, I even faster uninstalled it. It was just crap. Nowhere near useable. Nice idea, but since we already have a dotultimate license, I stay with Rider or ReSharper for VS.
finally, thx!
I weiss, es geht hier nicht um eine Wahl mit Excel Fehler, aber vielleicht kann @martinthuer.at hierzu auch was auswerten und den og Artikel hier wien.orf.at/stories/3342... aufwerten wenn man solche infos hier

It's been a while I shall have completed FSharp.MongoDB - but literally had no time to spend on fixing a stack overflow.
Now it is feature complete and fully supports NRT 🎉
Enjoy F# + MongoDB ! #fsharp #mongodb

With "dotnet project convert" we go from File-based app to project. But what if we start with a normal project, and then we want to convert it to a File-based app? I have created a small .NET tool for this: github.com/marcominerva.... And you can run it using dnx! #dotnet /cc @damianedwards.com
c’mon, cut them some slack...M$ has been sooo busy shipping the truly crucial features, like ramming AI into every corner nobody asked for. Who needs record highlighting when you can have Copilot in Notepad?

New reference article detailing lots of info about running C# file-based apps via `dotnet run` now available! Makes for great input to a coding agent when working on file-based apps.

Nice one👏
Everything about #dotnet File-based apps in one place.
Great starting point👇
In .NET 10 you can run C# files as scripts, but imagine sharing scripts in GitHub repos and then executing them by owner/repo and path… Cool stuff!

Blazor vs React: Why This .NET Architect Finally Picked a Side
Blazor vs React is a question every .NET developer eventually asks. Blazor lets you build interactive web UIs with C# instead of JavaScript. If you're already a .NET developer, this means one language, one ecosystem, …

I am genuinely SUPER EXCITED to announce that support for C# file-based apps (aka FBAs, new in #dotnet 10) is now enabled in the C#/C# Dev Kit extensions for @vscode.dev *by default*! We're going to continue refining & improving this experience over the coming months so update today!
