Open-sourcing the Calculator means that anyone in the community will be able to access and modify the source code to improve the user experience of the app. The code is now available in GitHub, and it includes, the source code, build system, unit tests, and Microsoft is even sharing the product roadmap, which developers can use to improve the app or integrate the Calculator logic and interface elements into their own apps. However, once changes are made to the app, Microsoft won’t just push them directly to users. The company will continue its usual testing, compliance, security, and quality processes before changes make it to the final product.
