Microsoft’s Calculator app is joining today the many other tools that the company has open sourced in recent years. The source code for the Calculator app is now available on GitHub under the MIT License, and Microsoft is now welcoming contributions from developers.

“Our goal is to build an even better user experience in partnership with the community. We are encouraging your fresh perspectives and increased participation to help define the future of Calculator,” the company explained in a blog post today, adding that checking the source code for the Calcultator app is a great way for developers to learn about Microsoft technologies like UWP apps, XAML, and Azure Pipelines.

The Open Sourcing of Windows Calculator won’t change anything for existing users, and the app will continue to ship with Windows 10. “Calculator will continue to go through all usual testing, compliance, security, quality processes, and Insider flighting, just as we do for our other applications,” the company assured.

Do you think open sourcing the app could make it evolve faster, and would you like Microsoft to do the same for other Windows 10 apps? Sound off in the comments below.
