Build and Learn ASP.NET 6.0 Blazor Hands-On - Learn Asynchronous Programming Through Coding Examples

This video tutorial provides an in-depth look at asynchronous programming fundamentals, focusing on ASP.NET Core and Blazor. It explains the Task class and async operations, demonstrating how to create and run an asynchronous console application using Visual Studio 2019. The tutorial covers the use of async and await keywords, illustrating their role in non-blocking operations. It concludes with a summary of key concepts and the purpose of the WaitAll method in the Task class.

Why is asynchronous programming important in ASP.NET Core and Blazor?

• It is required for all .NET applications.

• It simplifies the code structure.

• It helps in managing multiple tasks without blocking the main thread.

• It allows for faster execution of code.

What does the Task class represent in asynchronous programming?

• A method to handle exceptions in code.

• A sequence of operations executed one after another.

• A synchronous operation that returns a value.

• An asynchronous operation that does not return a value.

Which of the following is an example of an asynchronous operation?

• Reading a file line by line.

• Juggling multiple balls simultaneously.

• Executing a loop in a program.

• Printing a document.

In the async-await demo, what happens when the await keyword is used?

• The task is executed synchronously.

• The program stops executing until the task is complete.

• The task is canceled immediately.

• The control returns to the caller without waiting for the task to finish.

What is the purpose of the Task.WaitAll method?

• To prioritize tasks based on their importance.

• To cancel all running tasks.

• To wait for all provided tasks to complete execution.

• To execute tasks in parallel.

How does the async keyword affect a method?

• It prevents the method from returning any value.

• It automatically optimizes the method for performance.

• It makes the method execute synchronously.

• It allows the method to be executed asynchronously.

What is the result of a long-running operation in the demo?

• The operation returns immediately.

• The operation blocks the main thread.

• The operation finishes after a delay and returns a string.

• The operation fails to execute.
