NamedServices.Microsoft.Extensions.DependencyInjection

Allowes you to use Named Services with Microsoft Dependency Injection.
Supports string or enum as key.

Add Named Service to DI

There are a few ExtensionMethods for IServiceCollection, to add Named Services:

AddNamed
AddNamedSingleton
AddNamedScoped
AddNamedTransient
TryAddNamed
TryAddNamedSingleton
TryAddNamedScoped
TryAddNamedTransient

You can find the complete List of ExtensionMethods at the bottom of the README.

Resolve Named Service from DI

There are a few ExtensionMethods for IServiceProvider, to resolve Named Services:

GetNamedService
GetRequiredNamedService

Example

You can find to complete Example (an ASP.Net Core 3.0 Example) in the Folder Examples.

LiteDbRepoNames.cs

public enum LiteDbRepoNames {
    Users,
    Clients
}

Startup.cs

 public void ConfigureServices(IServiceCollection services) {

    ...

    services.AddNamedSingleton("users", sp => {
        var repo = new LiteRepository("Filename=users.db");
        repo.Database.Mapper.Entity<UserDbModel>().Id(model => model.Username, false);
        return repo;
    });

    services.AddNamedSingleton(LiteDbRepoNames.Clients, sp => {
        var repo = new LiteRepository("Filename=clients.db");
        repo.Database.Mapper.Entity<ClientDbModel>().Id(model => model.Name, false);
        return repo;
    });
    
    ...

}

TestController.cs

[Route("api/test")]
public class TestController: Controller
{
    private LiteRepository UsersRepo { get; }
    private LiteRepository ClientsRepo { get; }

    public TestController(IServiceProvider serviceProvider) {
        UsersRepo = serviceProvider.GetRequiredNamedService<LiteRepository>("users");
        ClientsRepo = serviceProvider.GetRequiredNamedService<LiteRepository>(LiteDbRepoNames.Clients);
    }

    ...
}
