Learn about CoreCLR and .NET Core

The best ways to learn about CoreCLR are to try out the product instructions and to read the "Book of the Runtime" architecture documents that describe the inner workings of the product. New devs to the CLR team are encouraged to read these documents before making substative changes to the product. They are equally useful for open source contributors.

.NET Core is part of ASP.NET 5 and is a subset of the .NET Framework. You can learn more about .NET Core and how and where you can use it in the CoreCLR is open source blog post.

The .NET Core Libraries repo contains the base class libraries, which provides data types and base functionality (ex: String, Collections, HttpClient) on top of CoreCLR. The two repos together make up .NET Core. The .NET Core is Open Source and Introducing .NET Core blog posts describes our .NET Core OSS strategy and road map in more detail.

Engage, Contribute and Provide Feedback

Some of the best ways to contribute are to try things out, file bugs, and join in design conversations. You are encouraged to start a discussion by filing an issue, or starting a thread in the [.NET Foundation forums].
