VS Code 1.139 Released with 12x Faster AI Agent Session Loading
Microsoft has released Visual Studio Code version 1.139, introducing up to 12x faster initial loading for large AI Agent session lists and enabling AI Agents to run directly inside remote Dev Containers over SSH, Tunnels, or WSL. This release simplifies remote AI workflows by allowing agents to reuse established project toolchains inside containers without duplicate setup, while drastically improving UI responsiveness for developers managing hundreds of AI chat sessions. The performance acceleration stems from a centralized metadata directory that avoids reading every session database on startup, reducing initial list load times from 1.3s to 0.1s in tests with ~645 sessions. The release also adds a Compact View, empty group hiding, and inline session renaming via F2 or context menus in the Agents Window.
## BACKGROUND
A Development Container (Dev Container) uses Docker to package dedicated tools, libraries, and runtimes into a consistent environment for developers. Visual Studio Code Remote Tunnels and SSH extensions enable developers to connect securely to remote machines and virtual environments directly within the editor.
