Microsoft outs new Windows 11 native command-line utility. Revolutionizes native app making.

Microsoft has released Windows-native Coreutils and AI-powered Windows Development Skills, thus improving cross-platform and native app development.

At Build 2026 today, Microsoft has announced the general availability (G.A.) of Coreutils for Windows, which brings a native set of Linux-style command-line utilities aimed at simplifying cross-platform development workflows.

For anyone not familiar, coreutils (short for Core Utilities) are a fundamental component of GNU and Linux-based operating systems as they provide many of the basic commands used for things like file, shell, and text manipulation. These include utilities such as ls, cp, mv, rm, cat, and pwd are part of the GNU Core Utilities package and are considered as essential tools that devs and system admins use daily across Unix-like environments.

According to the company Coreutils for Windows will work similarly to its GNU counterpart and will allow developers to use familiar commands and command-line pipelines across Windows, Linux, macOS, containers, and the Windows Subsystem for Linux (WSL) without needing to rewrite scripts or adjust workflows.

The company notes that some utilities may overlap with existing Command Prompt or PowerShell commands, meanwhile others that depend on POSIX-specific functionality have been excluded since they could break Windows or aren't said to be helpful. The project is available through a dedicated GitHub repo at this link.

Aside from coreutils another very interesting feature was also announced at Build 2026 today that could potentially revolutionize native app development. Dubbed "Windows Development Skills", it is a new set of AI-powered development tools designed to help agents build and maintain Windows apps better.

According to the company, the Skills are intended to provide AI agents with up-to-date knowledge and guidelines necessary for native Windows app development, thus greatly reducing the risk of outdated or wrong recommendations without the need for human intervention. Hence, it sounds like vibe coding done right.

Microsoft plans to go "100% native" for Windows 11 apps so perhaps this will help massively accelerate that journey, and also aid in reducing unintended but glaring issues while doing that.

The project is based on WinUI 3 and the Windows App SDK and can be managed with the winapp CLI. You can find its dedicated repo here on GitHub. You can find the announcement blog post here on Microsoft's official website.
