Katalogo 1.0.0

Katalogo

Katalogo - Esperanto for Catalog

Assembly scanning and catalog support for Microsoft.Extensions.DependencyInjection. This allows you to define a Catalog in your projects which allows you to create a set of service registrations. This technique resembles the Registry in Structuremap and Module in Autofac.

This project was inspired by the Scrutor Library by Kristian Hellang Assembly scanning and decoration extensions for Microsoft.Extensions.DependencyInjection.

Installation

Install the Katalogo NuGet Package.

Package Manager Console

Install-Package Katalogo

.NET Core CLI

dotnet add package Katalogo

Usage

The library adds two extension methods to IServiceCollection:

• Scan - This is the entry point to set up your assembly scanning to search for classes deriving from Catalog.
• RegisterCatalog - This method is used to register a catalog directly without assembly scanning.

See Examples below for usage examples.

Examples

Scanning

In your project you create a public class deriving from Catalog.

  public interface ITest
    {
        void Hello();
    }

    public class Test : ITest
    {
        public void Hello()
        {

        }
    }

    public class TestCatalog : Catalog
    {
        public TestCatalog(IServiceCollection services) : base(services)
        {
            services.AddTransient<ITest, Test>();
        }
    }

In your startup or whatever entry point you use to wire up your ServiceCollection you can do the following.

    IServiceCollection services = new ServiceCollection();

    services.Scan(scan => scan.FromCallingAssembly().RegisterCatalogs());

This will register all classes deriving from Catalog into your ServiceCollection that are in the Calling Assembly.

Direct registration

You can also register your Catalog directly the following way:

    IServiceCollection services = new ServiceCollection();
    services.RegisterCatalog<TestCatalog>();
