+We follow the style used by the [.NET Foundation](https://github.com/dotnet/runtime/blob/master/docs/coding-guidelines/coding-style.md), with a few exceptions:
 
 - We do not use the `private` keyword as it is the default accessibility level in C#.
 - We use hard tabs over spaces. You can change this setting in Visual Studio for Windows via `Tools > Options` and navigating to `Text Editor > C#` and selecting the "Keep tabs" radio option. In Visual Studio for Mac it's set via preferences in `Source Code > Code Formatting > C# source code` and disabling the checkbox for `Convert tabs to spaces`.
