Can you explain how Windows Subsystem for Linux (WSL) works?

Windows Subsystem for Linux (WSL) is a compatibility layer for running Linux executables (ELF64) directly on Windows 10 and Windows 11. It allows running Linux distributions without the need for a virtual machine or dual boot.

How WSL works:

• WSL provides a compatible Linux kernel interface that translates Linux system calls into Windows NT kernel calls.
• WSL 1 uses system call emulation, enabling most Linux applications to run with good performance.
• WSL 2 uses a full Linux kernel running inside a lightweight virtual machine based on Hyper-V, providing full Linux compatibility and improved file system performance.

Thus, WSL allows developers to use Linux tools and environments directly within Windows, facilitating cross-platform development and working with Linux environments.
