How to properly handle exceptions in asynchronous C# methods using async/await?
I'm working on a project and hit a roadblock. I'm working on a C# application using .NET 5.0 and I'm working with an scenario with exception handling in asynchronous methods. I've noticed that exceptions thrown within an `async` method are not being caught in the `try-catch` block I've set up in the calling method. Here’s a simplified version of the code: ```csharp public async Task<string> GetDataAsync() { await Task.Delay(1000); // Simulating an asynchronous operation throw new InvalidOperationException("Data retrieval failed!"); } public async Task ExecuteAsync() { try { var result = await GetDataAsync(); Console.WriteLine(result); } catch (InvalidOperationException ex) { Console.WriteLine($"Caught an exception: {ex.Message}"); } } ``` When I call `await ExecuteAsync();`, I see the exception thrown but it never enters the `catch` block. Instead, the program terminates with the following behavior: ``` Unobserved task exception. The task was not awaited and crashed the application. ``` I’ve checked to make sure that the method is marked as `async`, and I'm using `await` correctly. I'm also aware that exceptions in asynchronous methods follow a different flow compared to synchronous methods, but I need to seem to grasp what I'm missing here. I've considered wrapping the `await GetDataAsync();` call in another `try-catch`, but it feels redundant. Can someone help clarify the best practice for handling exceptions in this scenario? Are there any pitfalls I should be aware of when using async/await in C#?
