Wait for async Task without wrapping exceptions in AggregateException

Wait for async Task without wrapping exceptions in AggregateException

When waiting for an async Task in C#, you can use the await keyword to wait for the task to complete. By using await, any exceptions thrown by the task will be propagated directly to the calling method, without being wrapped in an AggregateException.

Here's an example of how to wait for an async Task without wrapping exceptions in an AggregateException:

public async Task MyMethodAsync() { try { await MyOtherMethodAsync(); } catch (Exception ex) { // Handle the exception here } } public async Task MyOtherMethodAsync() { // Perform some asynchronous operation here }

In this example, we have a method called MyMethodAsync that calls another asynchronous method called MyOtherMethodAsync. We're using the await keyword to wait for MyOtherMethodAsync to complete, and wrapping it in a try-catch block to handle any exceptions thrown by the method.

If MyOtherMethodAsync throws an exception, it will be caught by the try-catch block in MyMethodAsync, without being wrapped in an AggregateException. This makes it easier to handle exceptions in a cleaner and more readable way.

Note that in order to use await, the calling method must be marked as async. Also, any method that returns an async Task should be named with a suffix of "Async" to indicate that it's an asynchronous method.
