.NET 8.0 has been refreshed with the latest update as of November 10, 2026. This update contains security fixes. See the release notes for details about updated packages.
How to obtain and install the update
This update is available on Microsoft Update for Windows client operating systems and available on WSUS and MU Catalog for Windows Server operating systems.
Download the update from the .NET 8.0 download page.
Follow the installation guidance for your operating system: Windows, Linux, or macOS.
Prerequisites
Your operating system must be supported by .NET 8.0. Meet the operating-system dependencies described in the installation guidance for your platform.
Update behavior
On Windows, the standalone installers install the new version before removing the previous installation. By default, the previous installation is removed after the update succeeds. Administrators can configure removal to be deferred or disabled. See Choose when previous versions are removed.
With the default removal behavior, installing the .NET 8.0.34 runtime replaces the .NET 8.0.33 runtime after the update succeeds.
If you use a package manager or a manual installation, follow the update instructions for that installation method. For .NET installations managed by Visual Studio, use the Visual Studio Installer.
Known issue
When upgrading the ASP.NET Core Hosting Bundle from 8.0.33 to 8.0.34, the previously installed ASP.NET Core Module (ANCM) may remain installed.
Restart Requirement
You may need to restart the computer after you apply this update if any affected files are being used. We recommend that you exit all .NET-based applications before you apply this update.
