Implement IOC and DI without third Party

Please look here :
http://joelabrahamsson.com/inversion-of-control-an-introduction-with-examples-in-net/
an introduction to Inversion of Control, using the Dependency Injection and Service Locator patterns, with simple examples in C#.

This site also has some interesting articles about the IoC & DI:
Dependency Inversion Principle, IoC Container, and Dependency Injection (Part - 1)[^]
Dependency Inversion Principle, IoC Container & Dependency Injection (Part - 2)
Dependency Inversion Principle, IoC Container, and Dependency Injection (Part - 3)
Dependency Inversion Principle, IoC Container, and Dependency Injection (Part - 4)

Below is a nice video which demonstrates Inversion of control and how its is different from DI (Dependency Injection):

I hope this will help you))
Good Luck!

I just implemented my custom IController methods. And then I used that class in Application_Start.

public class ControllerFactory : DefaultControllerFactory
{
public override IController CreateController(RequestContext requestContext, string controllerName)
{
IController controllerObject = null;

Type controllerType = GetTypeForController(controllerName);
if (controllerType != null)
{
IEmployee employee = new EmployeeService((IRepository) new Repository());
controllerObject = (IController)Activator.CreateInstance(controllerType, employee);
}
return controllerObject;
}


public override void ReleaseController(IController controller)
{
var disposable = controller as IDisposable;
if (disposable != null)
{
disposable.Dispose();
}
}

private static Type GetTypeForController(string controllerName)
{
string fullTypeName;
Type type = null;

var ioCDictionary = new Dictionary();
ioCDictionary.Add("Employee", "HRApplication.Controllers.EmployeeController,HRApplication");

if (ioCDictionary.TryGetValue(controllerName, out fullTypeName))
{
type = Type.GetType(fullTypeName);
}
return type;
}
}

Then in app start we need to have this code
ControllerBuilder.Current.SetControllerFactory(typeof(ControllerFactory));
