The cross platform and improved Azure Functions runtime is now generally available, allowing you to use your cross-platform .NET Core assets within your Functions apps. At the core of the Azure Functions runtime is the function host, re-written to run in .NET Core 2.1. This not only brings significant performance improvements, but also allows Functions to be written and hosted locally on all major platforms—Windows, Mac, and Linux.
This new version of Functions runtime also comes with some UX updates for a personalized quickstart experience, as well as better integration with local tooling (Visual Studio and VS Code) from the Azure portal.
