Microsoft has announced that support for .NET 8 and .NET 9 will end in November 2026. To give customers additional time to plan and complete their migration, we will continue supporting .NET 8 and .NET 9 through the end of 2026. Support for both versions will be officially discontinued with our February 2027 release.
We recommend transitioning applications to .NET 10 or later to benefit from the latest platform capabilities, performance improvements, and security updates.
Looking ahead, Telerik UI for Blazor is already compatible with .NET 11 preview versions, and we plan to provide full support for the official .NET 11 release in November 2026.
