Key points
- .NET 8 and .NET 9 end of support on November 10, 2026.
- Microsoft recommends upgrading to .NET 10 for ongoing support.
- Existing applications will still run but will not receive updates.
End of Support Date
Microsoft has announced that .NET 8 and .NET 9 will reach their end of support on November 10, 2026. This means no further servicing updates, security fixes, or technical assistance will be available for these versions. Developers are encouraged to transition to .NET 10, which is an LTS release supported until November 2028.
Support Policies for .NET Releases
.NET 8 is classified as a Long Term Support (LTS) release with a 36-month support lifecycle starting from its release in November 2023. Conversely, .NET 9 is a Standard Term Support (STS) release and will now receive 24 months of support instead of the previous 18. Both versions will end their support on November 10, 2026.
Implications of End of Support
Post November 10, 2026, applications built on .NET 8 or .NET 9 will continue functioning but will be without new security updates, exposing them to potential vulnerabilities. Developers and users will not have access to technical support for any issues arising from these unsupported versions.
Visual Studio Compatibility
Future updates for Visual Studio 2022 will mark the components of .NET 8 and .NET 9 as out of support. Users will need to retarget their projects to .NET 10 or later to ensure continued compatibility and support. Options to remove unsupported components will be available in Visual Studio.
Actions for Developers
For users relying on .NET 8 or .NET 9 applications, it is advised to consult with software developers or vendors for updated versions compatible with .NET 10. The upgrade process involves adjusting the TargetFramework property in project files to net10.0 and ensuring all development and hosting environments are updated accordingly.
