.NET Core Libraries (CoreFX)

The corefx repo contains the library implementation (called "CoreFX") for .NET Core. It includes System.Collections, System.IO, System.Xml, and many other components. You can see more information in Documentation. The corresponding .NET Core Runtime repo contains the runtime implementation (called "CoreCLR") for .NET Core. It includes RyuJIT, the .NET GC, and many other components. Runtime-specific library code - namely mscorlib - lives in the CoreCLR repo. It needs to be built and versioned in tandem with the runtime. The rest of CoreFX is agnostic of runtime-implementation and can be run on any compatible .NET runtime.

Source Index

.NET Core now has a source index: https://source.dot.net

How to Engage, Contribute and Provide Feedback

Some of the best ways to contribute are to try things out, file bugs, and join in design conversations. If you are having issues with the Full .NET Framework or .NET Runtime, the best way to file a bug is at Connect or through Product Support if you have a contract.

Want to get more familiar with what's going on in the code?

Looking for something to work on? The list of up-for-grabs issues is a great place to start. See some of our guides for more details:

We've also started to share some of our direction via more higher-level documentation, specifically:

You are also encouraged to start a discussion by filing an issue or creating a gist.

You can discuss .NET OSS more generally in the .NET Foundation forums.

Reporting security issues and security bugs

Security issues and bugs should be reported privately, via email, to the Microsoft Security Response Center (MSRC) secure@microsoft.com. You should receive a response within 24 hours. If for some reason you do not, please follow up via email to ensure we received your original message. Further information, including the MSRC PGP key, can be found in the Security TechCenter.

.NET Core Library Components

The repo contains the source for each of the assemblies that comprises .NET Core. Each Microsoft.* or System.* folder under src represents an individual library. Each such folder may contain a ref folder, which contains the source representing the "contract" or "reference assembly" for that library. It may also contain a src folder, which contains the source for some or all of the implementation for that library (some implementation may live in mscorlib in the coreclr repo, with the build tooling generating type forwards from the library assembly to mscorlib.)
It may also contain a test folder containing the tests associated with that library, whether the implementation source lives in corefx or in coreclr.

Daily Builds

Daily builds of .NET Core components are published to dotnet-core MyGet gallery. The latest version number of each library can be seen in that gallery.

License

.NET Core (including the corefx repo) is licensed under the MIT license.
