Can we request unity to create an instance that does not implement interface?

Question

I have public class i.e. public class Student and i am currently instantiating it using new i.e. Student st = new Student() keyword.

This class does not implement any interface.

Can i request Microsoft Unity to create an instance of this class?

I only know we can request IOC if that class implement interface.

Answer 1

yes, you can for example resolve it directly:

var container = new UnityContainer();
var s = container.Resolve(typeof(Student));

or you can register an Instance:

container.RegisterInstance(s);

which will be used if another class needs a Student instance in the constructor.
