 In current versions, MSBuild built-in tasks generally support clean cancellation. However, this is up to the task author, or the author of the target or the SDK that packages the targets and tasks. If the issue persists, you could try upgrading to the most recent versions of SDKs you're using to see if the task was updated to support cancelability.

If you're consuming a task from an SDK or a third-party provider of a target, then you can contact the owner and ask them to implement `ICancellableTask` in a future version of the task.
