Some times interfaces are annotated with @Component annotation. Then my obvious reasoning was that classes that implement such interface will be treated as components as well. But if I am right tha...

Can someone guide me to some basic tutorials on inversion of control (IoC)? (preferably .net/c#). I need some hands on code to wrap my head around it :)

Inversion of Control (IoC) can be quite confusing when it is first encountered. What is it? Which problem does it solve? When is it appropriate to use and when not?

With regular ASP.NET MVC pages, the repository is passed in to the constructor of the control. Then the tests can instantiate the controller passing in a mock repository. How can I do this with we...
