.NET Supported OS Policy

.NET is supported on multiple operating systems.

Supported .NET versions

The following documents describe supported operating systems:

.NET 9 supported OS versions

Out-of-support .NET versions

The following documents describe (historical) supported operating systems:

.NET 7 supported OS versions

Change Process

Operating system versions are added and go out of support on a regular basis. We record these changes in three places:

The support documents listed above
Monthly Update Announcements
OS support tracking issues

Lifecycle Policy

Each supported operating system has a lifecycle defined by its sponsor organization (for example, Microsoft, Red Hat, Debian, or Apple). The .NET team applies each of those lifecycle schedules to inform adding and removing support for operating system versions. Support is typically removed when an operating system goes out of mainline support, at which point we stop testing and supporting it, and support documents are updated to match.

Operating system policies and schedules do not always align well with the annual .NET schedule. We have sometimes supported both Windows and Linux versions after mainline (and possibly free) support has lapsed as a service to users to provide more time to transition to newer releases. The previous support documents are kept up to date and provide accurate information you can use to make your own support decisions.
