This is very big news, all major OS vendors that also have a role in C and C++ language tooling, now have diversified their options in systems programming languages for greenfield development.

Additionally we finally get some public news about the MSVC integration rumors regarding Rust.

I'm totally disgusted that my Visual Studio 2022 instance uses 2 Gigabytes (!!) of RAM to run. What the hell is it doing that it's using that kind of memory?

How about those morons solving that first before moving towards Rust. An IDE shouldn't have to use more than a 100MB of RAM tops. Anything more is inexcusable or needs a detailed explanation.

BTW Firefox uses 1.1GB RAM so it's not immune from criticism either.

Vs2022 is a $1k a year product

Mainly purchased by companies not individuals and will be run on workstation pcs with a decent amount of RAM

So your complaints about 2gb are in the minority I would say, as most users don’t care. So it’s not a Microsoft priority.

After all, they are stupid enough to pay $1k a year for an IDE per seat!!!

clangd alone uses 6 GB when working with Chromium’s codebase. Code indexes can be very large, even for a simple application. Out-of-the-box IDEs must index the standard library and keep it in memory.

The complaint can be applied to any modern software, unfortunately.

You're right, though I'm not sure about all modern software quite to that extent. VS does have a reputation for being bloated. Even startup is not super fast IMO.

I checked just now. A recent Delphi with a project open: 175-200MB. Water (our IDE, I work at RemObjects) about 300MB.

Sure, and the performance improvements across VS 2026 releases prove that it could be much better.

Are you thinking this augurs more interoperability features in C?

Why should it?

COM and WinRT (basically COM Next) are the way to do cross language Interoperability in Windows since VB 5 replaced VBX with OCX, it was a key feature in .NET Framework design, and revamped on Windows 8, when WinRT was introduced as the original design for .NET (Ext-VOS).
