Dependency Management

The Dependency Management is a very fast dependency injection and components container, with many interesting features, and without reflection.

Its allows you to make your project more extensible and modular.

Features

The project contains many extensions (eg - modularity) and nuances that are not described here, read the documentation.

Without any reflection. Only ( optional) code generation.
Faster than other popular same projects, such as Autofac , Niject, other.
Supports DotNet 6, 7, also Native AOT , Nullable.
The project is extremely modular and can easily be expanded from the outside, as it uses a components system.

Example

This example is very primitive and does not allow you to take into all the features of the project.

Dependency.cs

public sealed class Dependency { }

Service.cs

public sealed class Service
{
    private readonly Dependency _dependency;

    public Service(Dependency dependency)
    {
        _dependency = dependency;
    }
}

With Code Generator

Program.cs

await using var container = new Container()
    .WithStrategies()
    .WithProviders();

container.SetTarget<Dependency>().ToSingleton();

container.SetTarget<Service>().ToTransient();

var readOnlyContainer = container.ToReadOnly();

var service = readOnlyContainer.LastInstance<Service>();

Without Code Generator

Program.cs

await using var container = new Container().WithStrategies();

container.SetTarget<Dependency>()
    .With(_ => new())
    .ToSingleton();

container.SetTarget<Service>()
    .With(c => new(c.LastInstance<Dependency>()))
    .ToTransient();

var readOnlyContainer = container.ToReadOnly();

var service = readOnlyContainer.LastInstance<Service>();
