Async and Await in C#

Async and Await are keywords in C# used for writing asynchronous code. They help applications run faster by preventing blocking operations.

Why Async Programming is Important

Without async programming, applications can freeze while waiting for tasks like API calls or database queries. Async avoids this problem.

Key Concepts

• async keyword
• await keyword
• Task-based programming

Example

public async Task GetData()
{
    await Task.Delay(2000);
    Console.WriteLine("Data loaded");
}

Common Mistakes

• Forgetting to use await
• Blocking async calls with .Result

Real-world Use

Used in APIs, web apps, and database calls to improve performance.

Summary

Async and Await make C# applications faster and more responsive by handling tasks asynchronously.
