.NET 8 and .NET 9 Both Reach End of Support on November 10, 2026
Microsoft will end support for .NET 8 (LTS) and .NET 9 (STS) on the same day: November 10, 2026. After that date, no security patches will be issued for either runtime, leaving applications vulnerable. The only supported path forward is .NET 10, which is supported until November 14, 2028.
Meridian48 take
The simultaneous end-of-life for both LTS and STS versions is a reminder that LTS doesn't mean indefinite support, and teams should plan upgrades well ahead of the deadline.
