# Timeout

> [!NOTE]
> The Timeout attribute does not work from .NET 5 and upwards due to limitations in the runtime.
> Beginning in NUnit version 4.5, usage of Timeout attribute on .NET 5 or higher is reported as a failure.
> Starting from .NET 5, due to limitations in the runtime, the Timeout attribute works only partially. It will cancel the test
> for the purposes of test results reporting and scheduling of further tests, but the test's code will continue to run on the test's
> thread in the background. Starting from NUnit version 4.5, usage of Timeout attribute at all on .NET 5 or higher is reported
> as a failure.

If you want to cancel the Test in the same manner, use the [CancelAfter Attribute](./cancelafter.md).
It is cooperative cancelling, so your test needs to handle the CancellationToken.
