.NET 8 appears here mainly in the context of Microsoft's support lifecycle and upgrade planning. The tagged discussion covers the end of support for .NET 8 and .NET 9 on November 10, 2026, a Patch Tuesday, after which apps built on either runtime no longer receive security fixes, servicing updates, or Microsoft technical support.
