ASP.NET Core 6: how to to Inject Scoped Service into Singleton Service
I'm building a feature where I'm trying to figure out Does anyone know how to I've searched everywhere and can't find a clear answer... I tried several approaches but none seem to work. I'm working with ASP.NET Core 6 and I've come across an scenario with dependency injection. I have a singleton service that needs to access a scoped service, but I'm getting an exception. Here’s the relevant part of my code: ```csharp public interface IMyScopedService { } public class MyScopedService : IMyScopedService { } public interface IMySingletonService { } public class MySingletonService : IMySingletonService { private readonly IMyScopedService _myScopedService; public MySingletonService(IMyScopedService myScopedService) { _myScopedService = myScopedService; } } ``` In my `Startup.cs`, I am registering the services like this: ```csharp public void ConfigureServices(IServiceCollection services) { services.AddScoped<IMyScopedService, MyScopedService>(); services.AddSingleton<IMySingletonService, MySingletonService>(); } ``` When I run the application, I receive an behavior stating: `InvalidOperationException: want to consume scoped service 'IMyScopedService' from singleton 'IMySingletonService'.` I understand that the behavior is due to the way the lifetime of services works in ASP.NET Core, but I really need to access the scoped service within the singleton. I've tried creating a factory for the scoped service, but I need to seem to get that to work properly either. Here’s a quick attempt at that: ```csharp public class MySingletonService : IMySingletonService { private readonly IServiceProvider _serviceProvider; public MySingletonService(IServiceProvider serviceProvider) { _serviceProvider = serviceProvider; } public void SomeMethod() { using (var scope = _serviceProvider.CreateScope()) { var scopedService = scope.ServiceProvider.GetRequiredService<IMyScopedService>(); // Use scopedService here } } } ``` This seems to work, but I'm not sure if this is the best practice. Is there a more efficient or cleaner way to handle this scenario? Also, are there any potential performance implications of creating scopes this way? My development environment is Linux. Is there a better approach? This issue appeared after updating to Csharp 3.10. For context: I'm using Csharp on Windows 11. This is for a web app running on Ubuntu 22.04. For context: I'm using Csharp on Debian. Thanks for your help in advance!
