Microsoft has announced that the Windows Calculator app is being open sourced on GitHub. The GitHub project hosts the source code, build system, unit tests, and the product roadmap, which should give developers an idea about how the app works.
Microsoft said on a blog post that the Windows Calculator app will be available for open source community under the MIT License.
