CSharp-Simple-IoC-Container

A very small IoC container in C#.NET. Just created for learning purpose.

This is a simple C# Console Application that shows how you can create your own custom IoC Container in the easiest way.

WARNING: Please do not use this as your project IoC Container, It lacks many features and functionalities.

Usage

It's simple, Here are the steps:

1. Define your types and implementations.
2. Call Resolve method of the container to get desired implementation.
3. Use it!

So let's get started!

1. Register your types like as follows:

   var container = SimpleIoC.CreateInstance();
   container.For<IMessageService>().Inject<MessageService>();

Or even simpler use Register method:

container.Register<ILogger, Logger>();

2. Then resolve and get an instance of your type like this:

   var resolvedService = container.Resolve<IMessageService>();

3. It's done! Enjoy it.

   resolvedService.SendMessage("This is a simple IoC Container!");

You can use Singleton in order to prevent instantiating classes more than once. To do so, add the UseSingleton() into your container:

var container = SimpleIoC.CreateInstance();
container.UseSingleton();

By doing this, All of the objects just creating once.
