@ -10,7 +10,7 @@ The core of the `async` and `await` are the `Task<T>` class. When using it along
Once encountering `async` methods, the work will be queued in a thread-pool for execution, while the caller will continue its execution without waiting on the return values from the `async` methods. However, in most occasions, our UI and service rely on the values returned from the `async` methods: for example, when we query a local database using the `async` methods, we would eventually want to know what are the query results and act on them, synchronously. This is where the `await` keyword shall be used: if using the `await` keyword when invoking an `async` method, the caller will pause the execution until a result is returned from the `async` method, and meanwhile, the parent method will continue execution without waiting on the caller to finish. With that said, any method that uses `await` keyword have to be an `async` function itself -- this is enforced by the C# compiler as well, if using Visual Studio to write your C# code, the IDE will warn you if a method violate the `async-await` contract.
