Summary  
This chapter explains how to convert synchronous methods into asynchronous ones using the async keyword and Task/Task<T> return types, how to use await to run multiple operations concurrently without blocking, and how to return values from asynchronous methods.  

General domain of usage  
Retrieving data from the internet

### Important Points
- A task represents an asynchronous operation;
- We can use the `async` keyword to convert a method into an asynchronous method;
- An asynchronous method always returns a `Task` object;
- In order to return data from an asynchronous method, we use the `Task<T>` as the method's return value, where `T` is the datatype of the return value;
- The `await` keyword waits for an asynchronous task to be performed.


What keyword is used to pause a method until an asynchronous operation is complete?

This course will give you a solid foundation to begin making applications using .NET in C#. Covering console applications, asynchronous programming, web services, database fundamentals, and ADO.NET CRUD operations, you'll gain practical skills. From creating apps and handling exceptions to optimizing database access, this course ensures a robust understanding of essential .NET development concepts.
