.NET end-of-life — frequently asked
What .NET versions are still supported?

When does .NET 9 reach end of life?
.NET 9 reaches end-of-life on 10 Nov 2026 — about 5 months away. After that date it stops receiving security patches.
Is .NET end-of-life?
No — .NET still has supported release lines (10, 9, 8). But individual older versions are end-of-life, so what matters is the specific version you run.
How do I know when my .NET version reaches end of life?
Check the version you run on its product page, or monitor .NET on IsItPatched to get an email alert before the release line you use reaches end-of-life — so you can upgrade in time.
