Microsoft retired the Touch Develop platform in June 2019. Looking for its replacement? See Microsoft MakeCode Arcade and other MakeCode editors.
At Microsoft, we continually evaluate and invest in building the right tools to help every student learn the computer science skills they need to succeed in the future. We determined we needed to replace Touch Develop with MakeCode in order to provide a more holistic, hands-on computing education platform that will bring computer science to life through physical computing devices like the micro:bit and immersive experiences like Minecraft. We have designed several games-based courses that use MakeCode Arcade.
