Recursion in asynchronous programming

Asynchronous programming has become a cornerstone for developing responsive applications, especially when dealing with I/O-bound operations, such as network requests. When you combine recursion with asynchronous programming, you can handle complex tasks such as fetching and processing data from external APIs or managing video content across a network efficiently.

Async recursion allows you to perform recursive operations without blocking the main thread, ensuring that your application remains responsive. For example, when fetching video data from an external API where videos are organized into categories that may contain subcategories, you can process each category and its subcategories recursively without freezing the UI.

Here’s how you might write an asynchronous recursive function to process videos:

async Task ProcessVideosAsync(Category category)
{
    foreach (var subcategory in category.Subcategories)
...
