Shiny Extensions

Dependency Injection Extensions

• Source generate all attributed classes to a single add file - saves you the boilerplate
• Extension methods for registering a dependency against multiple interfaces
• Extension methods for startup tasks (different to hosted services that don't work on mobile)
• Supports multiple interfaces
• Supports open generics
• Supports keyed services

THIS:

using Microsoft.Extensions.DependencyInjection;
using Shiny.Extensions.DependencyInjection;

// given the following code from a user
namespace Sample
{
    public interface IStandardInterface;

    public interface IStandardInterface2;

    [Service(ServiceLifetime.Singleton)]
    public class ImplementationOnly;

    [Service(ServiceLifetime.Transient, "ImplOnly")]
    public class KeyedImplementationOnly;


    [Service(ServiceLifetime.Singleton)]
    public class StandardImplementation : IStandardInterface;

    [Service(ServiceLifetime.Scoped, "Standard")]
    public class KeyedStandardImplementation : IStandardInterface;

    [Service(ServiceLifetime.Singleton)]
    public class MultipleImplementation : IStandardInterface, IStandardInterface2;

    [Service(ServiceLifetime.Scoped)]
    public class ScopedMultipleImplementation : IStandardInterface, IStandardInterface2;


    [Service(ServiceLifetime.Scoped, "KeyedGeneric")]
    public class TestGeneric<T1, T2>
    {
        public T1 Value1 { get; set; }
        public T2 Value2 { get; set; }
    }
}

GENERATES THIS:

// <auto-generated />
using global::Microsoft.Extensions.DependencyInjection;
using global::Shiny.Extensions.DependencyInjection;

namespace Sample
{
    public static class __GeneratedRegistrations
    {
        public static global::Microsoft.Extensions.DependencyInjection.IServiceCollection AddGeneratedServices(
            this global::Microsoft.Extensions.DependencyInjection.IServiceCollection services
        )
        {
            services.AddSingleton<global::Sample.ImplementationOnly>();
            services.AddKeyedTransient<global::Sample.KeyedImplementationOnly>("ImplOnly");
            services.AddSingleton<global::Sample.IStandardInterface, global::Sample.StandardImplementation>();
            services.AddKeyedScoped<global::Sample.IStandardInterface, global::Sample.KeyedStandardImplementation>("Standard");
            services.AddSingletonAsImplementedInterfaces<global::Sample.MultipleImplementation>();
            services.AddScopedAsImplementedInterfaces<global::Sample.ScopedMultipleImplementation>();
            services.AddKeyedScoped(typeof(global::Sample.TestGeneric<,>), "KeyedGeneric");

            return services;
        }
    }
}

Stores

• Key/value store with support for
  • Android/iOS/Windows - Preferences & Secure Storage
  • Web - Local Storage & Session Storage
  • In Memory
• Object binder binds INotifyPropertyChanged against a key/value store to persist object changes across sessions
• Simply implement IKeyValueStore to create your own store

Web Hosting Extensions

• Merges service container build and post build scenarios into a single class
• All IInfrastructureModule implementations are automatically detected and run

Additional Libraries Used

• Shiny Reflector - Reflection without the actual reflection
