C# - How to properly use IDisposable with asynchronous methods and HttpClient in .NET 6?
I'm converting an old project and I'm learning this framework and I'm currently working with `HttpClient` in a .NET 6 application and trying to implement the `IDisposable` pattern correctly, especially in the context of asynchronous methods. I've read that `HttpClient` is intended to be reused but I've also seen recommendations for disposing of it to avoid socket exhaustion. I'm unsure about the best approach when my methods are asynchronous. Here's a simplified version of what I'm trying: ```csharp public class ApiClient : IDisposable { private readonly HttpClient _httpClient; private bool _disposed; public ApiClient() { _httpClient = new HttpClient(); } public async Task<string> GetDataAsync(string url) { if (_disposed) throw new ObjectDisposedException(nameof(ApiClient)); var response = await _httpClient.GetAsync(url); response.EnsureSuccessStatusCode(); return await response.Content.ReadAsStringAsync(); } public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } protected virtual void Dispose(bool disposing) { if (!_disposed) { if (disposing) { _httpClient.Dispose(); } _disposed = true; } } } ``` The scenario I'm working with is the `ObjectDisposedException` when multiple asynchronous calls are made to `GetDataAsync` if I dispose of the `ApiClient` after the first call completes. I tried to manage the disposal by using the `using` statement, but that leads to the `HttpClient` being disposed before all requests finish, resulting in errors. I've tried creating a single instance of `HttpClient` for the lifetime of the application instead of creating it each time, but I still need to dispose of my `ApiClient` properly. Should I be implementing a different pattern or restructuring my code? Any advice or best practices for managing `IDisposable` with async methods would be greatly appreciated! I'm working on a service that needs to handle this. Thanks in advance! I'm developing on Ubuntu 22.04 with C#. I'd love to hear your thoughts on this. My team is using C# for this mobile app. What am I doing wrong?
