Asynchronous programming in C# is a powerful way for creating efficient and responsive applications, it aims to improve the efficiency and responsiveness of applications by allowing multiple tasks to run concurrently. In this blog post, we’ll explore detail about the Asynchronous programming in C#.
What is asynchronous programming?
In traditional Synchronous programming, task executes one after other, your program waits for a task to finish before moving on to the next task.
For example: Waiting in a queue at a ticket counter; you have to wait for the person in front of you to finish buying their ticket before your turn.
On the other hand, Asynchronous programming changes that approach. Instead of waiting for one task to finish before starting another, it allows your program to start a task, and while it’s working on that, it can do something else.
For Example: It’s like having more than one worker in a kitchen, where each worker can handle a different task and each task are happening at the same time.
Let’s take a scenario where applications need to perform operations that take time, such as reading from a file or external drive, making a network request to access some resource, or querying a database.
In Synchronous code, the application would wait until the operation is complete, which could lead to unresponsiveness. Asynchronous programming addresses this challenge by allowing the application to continue executing other tasks while waiting for the time-consuming operation to finish.
Asynchronous vs. Synchronous Programming:
Here are the key differences between Asynchronous and Synchronous programming.
|It allows tasks to execute concurrently, that enables multiple operations to happen at the same time.||In this case, Tasks are executed sequentially; the program waits for each task to finish before moving on to the next one.|
|Asynchronous tasks do not block the program’s execution, the program can continue executing other operations while waiting for the task to complete.||Synchronous tasks block the program’s execution. When a synchronous task is initiated, the program waits until the task is finished before proceeding to the next line of code.|
|It enhances the responsiveness of an application and prevents the program from freezing.||It can make an application less responsive; the program may appear frozen or unresponsive until the current task is completed.|
|Asynchronous programming can utilize system resources more efficiently.||Synchronous programming uses system resources sequentially, each task occupies resources exclusively until it completes current task.|
