Canonical recently announces full support for Ubuntu on the Windows Subsystem for Linux (WSL) 2.
WSL 2 introduces lightweight virtualisation and a Linux kernel which provides the full set of capabilities needed for enterprise certification and support. These changes align Ubuntu on WSL with the Azure and AzureStack capabilities, greatly reducing friction for workflows which start on the Windows workstation and finish on Azure.
Ubuntu on WSL will include integrated Windows file sharing capabilities to simplify the developer experience with Windows-based IDEs and version control systems for Linux-built and operated apps. In addition, the integration of Active Directory and other Windows services with Ubuntu will simplify operations at scale in Microsoft environments.
