 If you don't know what a pull request is read this article: https://help.github.com/articles/using-pull-requests. Make sure that the repository can build and that all tests pass. Familiarize yourself with the project workflow and our coding conventions. The coding and style guidelines are described and enforced by `.editorconfig` as well as .NET Compiler Platform analyzers. These tools will automatically override your default settings without changing your environment. Violations will cause the build to fail.
