Exploring the .NET CoreFX (2014-2015)

On November 12, Microsoft announced that it will be releasing the .NET core as open source. The .NET core includes the Core Foundational Libraries (CoreFX), the Common Language Runtime (CoreCLR), and many other tools and libraries. The source code is available at GitHub athttps://github.com/dotnet.
