C# Async Await
0 likes688 views
The document explains asynchronous programming, highlighting its ability to allow applications to perform other tasks without waiting for a single task to complete, effectively preventing application blockage. It discusses the use of the async and await keywords in C# to facilitate asynchronous execution and contrasts asynchronous programming with synchronous programming, where tasks complete one after another. The document includes a demo and outlines the significance of asynchronous programming for I/O-bound and CPU-bound tasks.

- 5. What is Asynchronous Programming? Using asynchronous programming, the application can work on other tasks without waiting for the task to be completed. Asynchronous programming is very popular in C# thanks to the async and await keywords. When dealing with UI, we use a long-running method like reading a large file or something similar. If any synchronous process is blocked, the entire application is blocked, and our application stops responding until the task is completed.
- 7. Need of Asynchronous Programming In Synchronous Programming, compilers run one statement and wait for it to complete and then move to next one In Asynchronous Programming, compilers run one statement and while it gets completing, we will also work on the next one

- 10. Async and Await Keyword Async Keyword Asynchronous methods are created by using the async modifier on a method. An async method runs synchronously until it reaches its first await operator, at which point it suspends. An async method runs synchronously until it reaches its first await operator, at which point it suspends.
- 11. Async and Await Keyword Await Keyword While the asynchronous operation is running, the await operator suspends the async method evaluation. When the asynchronous operation completes, the await operator returns the result.
