This helps improve performance and responsiveness, especially in modern applications.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is Async \/ Await<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Async and Await are keywords in C# used to handle long-running operations like file access, database calls, or web requests without freezing the application.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why Async \/ Await is Used<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">They allow programs to perform multiple operations efficiently without waiting for each task to complete before moving to the next.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How Async \/ Await Works<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The async keyword is used to define a method as asynchronous. The await keyword pauses the method execution until the task completes, without blocking the main thread.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Async Method<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">An async method returns a Task or Task&lt;T&gt; and allows asynchronous operations inside it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Await Keyword<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Await is used to wait for a task to complete while allowing other operations to continue.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Non-Blocking Execution<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Async programming ensures that the application remains responsive, especially in UI and web applications.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Importance of Async \/ Await<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It improves application performance, enhances user experience, and allows efficient resource utilization.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Real World Usage<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Async and Await are used in web APIs, database operations, file handling, network calls, and cloud applications.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Advantages<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Improves performance<br>Keeps applications responsive<br>Efficient resource usage<br>Simplifies asynchronous code<br>Supports modern programming<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Common Mistakes<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Forgetting to use await<br>Blocking async code with synchronous calls<br>Not handling exceptions properly<br>Overusing async unnecessarily<br>Ignoring task results<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Best Practices<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Use async for long-running tasks<br>Always use await properly<br>Handle exceptions carefully<br>Avoid blocking calls like .Result or .Wait()<br>Write clean and readable async code<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Lesson Summary<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Async and Await in C# enable non-blocking operations, making applications faster and more responsive.
