.NET Core Dependency Injection Named Extensions

Extensions for .NET Core Dependency Injection container, that allow to resolve dependencies by key.

Why?

Current implementation of .NET Core Dependency Injection container does not support registration and resolving dependencies by name or key.

Installation

Can be installed via Nuget

Install-Package DependencyInjection.Extensions.NamedDependencies

or .NET CLI

dotnet add package DependencyInjection.Extensions.NamedDependencies

Usage

Register named services with IServiceCollection

services.AddScoped<IEventBus, AzureServiceBusPersistance, string>("azureServiceBus");
services.AddScoped<IEventBus, RabbitMQServicePersistance, string>("rabbitMQ");

Inject IServiceProvider interface where you need to resolve dependency and call GetService method with key provided

var eventBus = serviceProvider.GetService<IEventBus, string>(eventBusKey);

Note

Not only string can be used as type for key parameter. All extensions is parameterized, so Enum, Guid or another types can be used as key.

Dependencies

This extensions are built with .NET Standart 2.0 and depends on Microsoft.Extensions.DependencyInjection

Versioning

DependencyInjection.Extensions.NamedDependencies follows the versioning of the Microsoft.Extensions.DependencyInjection, since it's main dependency.
