What are the best practices for cancellation in C#?

In C#, the best practices for cancellation involve using the CancellationToken and CancellationTokenSource classes. This allows you to signal cancellation requests to running tasks.

Can you explain how to implement a CancellationToken in a task?

Sure! You can pass a CancellationToken to a task by including it as a parameter. Inside the task, you can check the token's IsCancellationRequested property to determine if cancellation has been requested.

What happens if I don't check for cancellation in my tasks?

If you don't check for cancellation, your tasks may continue running even after a cancellation request, which can lead to resource leaks or unresponsive applications.

Are there any specific scenarios where cancellation is particularly important?

Yes, cancellation is crucial in scenarios like long-running operations, user-initiated actions, or when managing resources that need to be released promptly.
