SimpleDependencyResolver 1.0.0

SimpleDependencyResolver

A lightweight library for dependency registration using annotation attributes in .NET.

📝 Description

SimpleDependencyResolver enables dependency registration through attributes, simplifying your DI container setup. The project is split into two packages:

• SimpleDependencyResolver: Core library with resolver implementation
• SimpleDependencyResolver.Abstractions: Contains only attributes, suitable for class libraries without unnecessary dependencies

✨ Features

• Automatic dependency registration
• Support for different lifetimes:
  • Transient
  • Scoped
  • Singleton
• Keyed services support for .NET 8+
• Compatible with .NET Standard 2.1 and higher
• Separated abstractions for class libraries

🚀 Installation

For projects implementing services:

dotnet add package SimpleDependencyResolver.Abstractions

For projects that need to register dependencies:

dotnet add package SimpleDependencyResolver

📋 Usage

1. In your class library, add the abstractions reference and use attributes:

using SimpleDependencyResolver.Attributes;

[Scoped]
public class MyService : IMyService
{
    public string GetData() => "Hello from MyService";
}

2. In your startup project, add the main reference and register the resolver:

using SimpleDependencyResolver;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddSimpleDependencyResolver();

3. Alternatively, you can register the resolver with a specific assembly:

using SimpleDependencyResolver;
using System.Reflection;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddSimpleDependencyResolver(Assembly.GetExecutingAssembly());

Using Keyed Services (.NET 8+)

[Scoped(ServiceKey = "primary")]
public class PrimaryService : IMyService
{
    public string GetData() => "Primary Service";
}

[Scoped(ServiceKey = "secondary")]
public class SecondaryService : IMyService
{
    public string GetData() => "Secondary Service";
}

// Inject using IKeyedServiceProvider
public class Consumer
{
    private readonly IMyService _primaryService;
        
    public Consumer([FromKeyedServices("primary")] IMyService service)
    {
        _primaryService = service;
    }
}
