.NET Core Supported OS Lifecycle Policy

# .NET Core Supported OS Lifecycle Policy

## Summary

.NET Core is supported on a range of operating systems and versions. Each platform has distinct Lifecycles defined by the parent organization. .NET Core support will take these Lifecycle schedules into account when adding or removing versions from the supported list.

## Details

.NET Core supports a set of operating systems. When a new .NET Core version is released, it will typically support the latest version of each operating system, for example Fedora 26. If a new operating system version is released afterwards, for example Fedora 27, it will typically be supported when the next .NET Core version is released.

'Support' means that .NET Core is built and tested on the OS, security and other updates will be made available and Microsoft Developer Support may be contacted for assistance with .NET Core on the environment.
