Handling Multiple Dependency Registrations in ASP.NET Core with Autofac - Conflicting Services guide
I'm migrating some code and I'm optimizing some code but I'm building a feature where I tried several approaches but none seem to work... I'm currently working with a scenario with service registrations in my ASP.NET Core application using Autofac. I have two services, `IRepository<User>` and `IRepository<Product>`, both of which are implemented by the same class `Repository<T>`. My application is set up to use Autofac for dependency injection, but I'm working with an `InvalidOperationException` indicating that the type 'IRepository<User>' has already been registered when I try to resolve the `IRepository<User>` service. Here’s how I’m currently registering my services in the `Startup.cs`: ```csharp public void ConfigureServices(IServiceCollection services) { services.AddControllers(); } public void ConfigureContainer(ContainerBuilder builder) { builder.RegisterGeneric(typeof(Repository<>)).As(typeof(IRepository<>)); } ``` I thought using `RegisterGeneric` would allow me to register the generic repository for both `User` and `Product`, but it seems like Autofac is getting confused when I try to resolve them. This is the behavior I'm seeing: ``` Autofac.Core.Registration.ComponentAlreadyRegisteredException: The type 'IRepository<User>' is already registered. ``` To troubleshoot the scenario, I've tried changing the registration order and made sure I'm not accidentally registering `Repository<User>` or `Repository<Product>` directly elsewhere in my code. I've also looked into using `AsSelf()` or `AsImplementedInterfaces()` but that doesn't seem to solve the conflict. Can anyone guide to understand why this registration conflict is occurring and how I can resolve it? I'm using ASP.NET Core 6.0 along with Autofac 6.0.0. Any help would be greatly appreciated! This is my first time working with C# latest. Thanks for any help you can provide! Could this be a known issue?
