C# 11 - Difficulty Using Dependency Injection with Scoped Services in Background Hosted Services
Quick question that's been bugging me - I'm building a feature where I'm experimenting with This might be a silly question, but Hey everyone, I'm running into an issue that's driving me crazy... I'm currently working with an scenario with scoped services in a background hosted service in my ASP.NET Core application. I have a background service that needs to access a scoped service to fetch some data from the database. However, I'm working with a `InvalidOperationException` stating that 'want to consume scoped service 'MyScopedService' from root provider'. I understand that scoped services are meant to be used within a request scope, but I thought the `IServiceScopeFactory` would allow me to create a new scope within my hosted service. I've set up my background service like this: ```csharp public class MyBackgroundService : BackgroundService { private readonly IServiceScopeFactory _scopeFactory; public MyBackgroundService(IServiceScopeFactory scopeFactory) { _scopeFactory = scopeFactory; } protected override async Task ExecuteAsync(CancellationToken stoppingToken) { while (!stoppingToken.IsCancellationRequested) { using (var scope = _scopeFactory.CreateScope()) { var myScopedService = scope.ServiceProvider.GetRequiredService<MyScopedService>(); await myScopedService.ProcessDataAsync(); } await Task.Delay(TimeSpan.FromMinutes(5), stoppingToken); } } } ``` I've registered `MyScopedService` in my `Startup.cs` like this: ```csharp services.AddScoped<MyScopedService>(); services.AddHostedService<MyBackgroundService>(); ``` When I run the application, I still receive the `InvalidOperationException`. I've checked that the service is being registered properly, and I even tried using `AddSingleton` for `MyScopedService`, but that caused other issues with data consistency. Is there a specific way to handle scoped services inside a background service, or am I missing a configuration step? Any insights would be greatly appreciated! What's the best practice here? I'm working on a API that needs to handle this. I'm working in a Debian environment. Any ideas what could be causing this? I'm working on a web app that needs to handle this.
