What is asynchronous programming in .NET Core and why is it important?
Updated Apr 28, 2026
Short answer
Async programming allows non-blocking operations using async and await keywords.
Deep explanation
Async/await enables efficient use of threads by freeing them while waiting for I/O operations. This improves scalability and responsiveness, especially in web applications handling many concurrent requests.
Real-world example
Handling multiple API requests in parallel without blocking server threads.
