Your comment couldn't be more wrong. .NET Core is an open platform, and has been for some time, with its framework and runtime hosted on GitHub. .NET Core's toolchain is a simple CLI which integrates with many popular CI/CD solutions (e.g., TeamCity). .NET Core has been stable on several Linux distros for many months and can hardly be characterized as "experimental." C# has a cross-platform, lightweight editor in VSCode--no Visual Studio required.

I suggest you update your knowledge before spreading blatantly incorrect information like this.
