My favorite .NET 10 feature so far is not within the .NET library itself, but `dotnet tool exec` to run C# files as scripts without a build step. This has been available in F# for a long time via `dotnet fsi`, and for C# also via the third party cs-script tool. It took a surprisingly long time to officially reach the primary .NET language! I only really wish C# would’ve been directly integrated as an alternative scri…

"dotnet tool exec" is not that feature; you're thinking of https://devblogs.microsoft.com/dotnet/announcing-dotnet-run-... which they added to "dotnet run". "dotnet run my-cool-thing.cs" "dotnet tool exec" is so you can run third party command line tools like csharpier that previously required "dotnet tool install" before you could use them. For example, in https://csharpier.com/docs/Installation you can now simply d…

Ah yes, that's the one I was thinking of. Got confused by this article.

The issue was in the beginning they didn’t think interop with C/C++ was value add. People complained and they added “Managed C++” which unfortunately influenced C++03’s design a lot. It wasn’t until C++11 that Microsoft gave up. You couldn’t effectively interop with C++ without writing a managed C++ wrapper, which only worked on windows. They added support for P/Invoke to aid in Win32 calls (shell.dll, user32.dll) as…

You are jumping over a few facts there. P/Invoke was born as J/Direct on J++, it became P/Invoke after the lawsuit, and Cool project turned into C#. Managed C++ Extensions in .NET 1.0 got replaced by C++/CLI on .NET 2.0, it was a .NET Core 3.1 milestone to support it, and has recently been updated up to C++20, minus modules. Still heavily used among .NET community on Windows. Meanwhile the native C++/CX and C++/WinRT…

I only wish if C++/CLI worked on other platforms...

I guess LinqPad will lose some users to this feature.

This isn't LinqPad's selling point. All that dotnet run *.cs has done is remove the need to have a project file for each "script" you write. LinqPad maybe has this feature but it's selling point is as a scratch pad to experiment with working with data and general futzing around.

The .NET team said they're working on VS Code integration. LinqPad still has some unique features (mostly database related), but at least for me, VS Code + dotnet run will be sufficient for my needs. Worst case, I can just throw a breakpoint on my database IQueryable result.

Since you mention great CLI - is there a CLI tool that is free/cross platform that works like prettier ? I found https://csharpier.com/ but have never heard of anyone using it. Also not sure how it works with linters like roslynator or stylecop ? This is something I miss very much when coming back from TS, other languages also have better formatters. C# is very tied to editors/IDEs which is a nightmare in teams where…

dotnet format [0] exists and is maintained by the .NET team. It is different from Prettier in that it is much more configurable, but it gets the job done for us. It does integrate language services and can automatically apply code fixes for custom analyzers. I have not explicitly tried roslynator or stylecop, but I suspect this would work as expected.

I was not able to use (recent) dotnet-format as standalone .exe tool, also it only worked if inside an actual project with .sln/.slnx file and all that. I could not instruct it to work on single file.

I've wanted this for a long time. After reading this link, and the MS release announcement, I still don't understand what a "tool" is, or how you can use `tool exec` to run a single *.cs file. Is there a straight-forward recipe anywhere for doing this targeted at absolute simpletons?

Sorry for confusing you. I can't edit the post now. The command is dotnet run script.cs. The tool stuff is about something else unrelated; NuGet installable CLI executables.

You can divide visual studio into 4 era's. The vs6 (we smashed all of our dev tooling together and its integrated decently) era, the vs2002/vs2003/vs2005 (we broke it all and you will like it and never speak of C++ again), vs2010 era (we fixed all of that from 2002 sorry about that), vs2017/vs2022 (it updates from the internet and takes forever to install and now does everything). The problem is MS is unwilling to st…

VS2017 was the introduction of the modern VS installer that is way faster than the prior ones.

Also (since 2015) forward/backward (to a degree) CRT compatibility.

https://learn.microsoft.com/en-us/cpp/porting/binary-compat-...

This saved so much time, space and support - where previously we had to recompile stuff, and if you had Maya/MotionBuilder/etc plugin it had to use the right compiler.

Also now even with newer IDE you can instruct the project to use older (or even better - a specific) version of the toolchain.

I very much doubt about TS.Net, given the rewrite in Go decision. .NET nowadays has a serious adoption problem, and they should spend more time talking with their own colleagues at Azure, about their use of Java, Go, Rust.

I would not touch C# unless you are already using it. Microsoft proves over and over it cannot be trusted in what they say. Watch what they do: - basically dont use ant UI framework they say is the future and they are not using themselves - be vary of the future of some of it stuff like C#

Do you know about any sizeable open source projects written in C#, other than what Microsoft has produced? I rarely come across anything written in it.

https://github.com/MonoGame/MonoGame (runs even on consoles, which is rare for open source game frameworks and engines) https://github.com/SubtitleEdit/subtitleedit https://github.com/jellyfin/jellyfin https://github.com/AvaloniaUI/Avalonia https://github.com/bitwarden/server https://github.com/unoplatform/uno https://github.com/files-community/Files https://github.com/NickeManarin/ScreenToGif https://github.com/DevT…

The FFXIV extension/mod tool is a fun example.

.NET was the most sane programming ecosystem that I worked in. Great CLI, great package manager, very good stdlib, strong IDEs/Debuggers, etc. but sadly interesting jobs like OSes, databases and compilers are way less common than in C++ world :(

I despise working with Nuget. Whether it's a restore, managing your csproj, or publishing packages, compared to NPM it's an absolute mess.

Only thing I want to hear about lately is the next major version of Visual Studio, I feel like it will never come. I always feel like every major version has drastic improvements, and I'm starved for them.

Maybe they will use this chance to finally switch it away from the .NET Framework to the modern dotnet runtime with its many years optimizations.
