Hasim.Injectify 0.1.1

Injectify

A modular dependency injection system for ASP.NET Core applications. Automatically discovers modules across all projects in a solution — no manual registration needed.

Concept

Each project in your solution (Application, Core, EF Core, UI, etc.) defines its own module that registers its own dependencies. The host project (UI) discovers and initializes all modules automatically with just two calls:

// Program.cs — only 2 lines needed
var builder = WebApplication.CreateBuilder(args);
builder.InjectifyApplication();
// ...
var app = builder.Build();
app.InjectifyInitializer();
app.Run();

Features

Installation

dotnet add package Injectify

Quick Start

1. Create a module in each project

using Injectify.Modules;

[ModuleInfo("My Module", "1.0.0", "Description of the module")]
[ModuleOrder(10)]
public class MyModule : BaseInjectifyModule
{
    public override void ConfigureService(IServiceCollection services, IConfiguration configuration)
    {
        services.AddScoped<IMyService, MyService>();
    }

    public override void ConfigureApplication(WebApplication app)
    {
        app.Logger.LogInformation("MyModule initialized");
        app.UseMiddleware<MyMiddleware>();
    }
}

2. In the UI project — 2 lines

var builder = WebApplication.CreateBuilder(args);
builder.InjectifyApplication();    // Scans all assemblies, discovers all IModule

var app = builder.Build();
app.InjectifyInitializer();            // Calls ConfigureApplication on each module
app.Run();

3. Module lifecycle

public class MyModule : BaseInjectifyModule
{
    public override void OnInit(IServiceCollection services) { /* before registration */ }
    public override void OnStart(WebApplication app)        { /* after build, before run */ }
    public override void OnStop()                           { /* on shutdown */ }
}

4. Module dependencies

[DependsOn(typeof(CoreModule))]
[DependsOn(typeof(EFCoreModule))]
public class UIModule : BaseInjectifyModule { }
