Aoxe.DependencyInjection.Extensions 2024.1.0

Aoxe.DependencyInjection.Extensions

Aoxe.DependencyInjection.Extensions provides extension methods for Microsoft's Dependency Injection container to simplify service registration with Lazy<T> support. These extensions allow for deferred instantiation of services, improving performance by delaying object creation until it's actually needed.

Features

• Extension methods to register services with Lazy<T>
  • AddSingletonWithLazy
  • AddScopedWithLazy
  • AddTransientWithLazy
• Support for both type and factory-based registrations
• Simplifies the use of Lazy<T> in dependency injection scenarios

Installation

To install the package, add the following to your project file:

<PackageReference Include="Aoxe.DependencyInjection.Extensions" Version="2024.1.0" />

Or use the .NET CLI:

dotnet add package Aoxe.DependencyInjection.Extensions

Usage

First, include the namespace:

using Aoxe.DependencyInjection.Extensions;

Registering Services

Singleton Services

Use the 'AddSingletonWithLazy' method to register singleton services with Lazy<T> support:

services.AddSingletonWithLazy<IMyService, MyServiceImplementation>();

Scoped Services

For scoped services, use the 'AddScopedWithLazy' method:

services.AddScopedWithLazy<IMyService, MyServiceImplementation>();

Transient Services

For transient services, use the 'AddTransientWithLazy' method:

services.AddTransientWithLazy<IMyService, MyServiceImplementation>();

Accessing Services

Inject Lazy<T> into your classes to defer service instantiation:

public class MyController
{
    private readonly Lazy<IMyService> _myService;

    public MyController(Lazy<IMyService> myService)
    {
        _myService = myService;
    }

    public void DoWork()
    {
        // The IMyService instance is created only when accessed
        _myService.Value.PerformOperation();
    }
}
