Asynchronous programming
The Task asynchronous programming model (TAP) provides an abstraction over asynchronous code. You write code as a sequence of statements, just like always. You can read that code as though each statement completes before the next begins. The compiler performs many transformations because some of those statements may start work and return a Task representing the ongoing work.
In C#, Task.Delay
and Thread.Sleep
are both used to introduce delays or pauses in the execution of your code, but they have different use cases and implications.
In summary, use Task.Delay
when working with asynchronous code and you want to avoid blocking the current thread. Use Thread.Sleep
when you explicitly want to block the current thread, but be cautious about using it in scenarios where responsiveness is important, such as in GUI applications. In modern C# applications, with the widespread use of async/await, Task.Delay
is often the more appropriate choice.
