Or we may choose to exclude a supported platform for specific reasons. +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. -One example is Windows 7 SP1. Windows 7 SP1 is out of support, but enterprise customers can buy [Extended Security Updates](https://docs.microsoft.com/troubleshoot/windows-client/windows-7-eos-faq/windows-7-extended-security-updates-faq), and many do. Given the widespread use of Windows 7 in the .NET ecosystem we chose to include Windows 7 SP1 (with Extended Security Updates installed) as a supported platform for .NET 5.0. Another example is Windows Server 2012. Windows Server 2012 is currently in support but not included in the supported platform list for .NET 5.0 because a newer version is available in the Server 2012 family - Server 2012 R2. +Operating system policies and schedules do not always align well with the annual .NET schedule. We have sometimes supported both [Windows](https://docs.microsoft.com/troubleshoot/windows-client/windows-7-eos-faq/windows-7-extended-security-updates-faq) 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. |
