What are some advanced topics in async programming with C#?

Advanced topics in async programming with C# include async streams, cancellation tokens, and the use of ValueTask.

Can you explain async streams and how they differ from regular async methods?

Async streams allow you to asynchronously iterate over a sequence of values using the IAsyncEnumerable<T> interface, which is different from regular async methods that return a single value.

What are cancellation tokens and how do they work in async methods?

Cancellation tokens are used to signal that an operation should be canceled. They allow you to gracefully stop long-running tasks in async methods.

How can I improve the performance of my async code?

You can improve performance by minimizing context switching, using ValueTask instead of Task when appropriate, and avoiding blocking calls.
