What Is Task<>? Where is the difference bewteen controller and razor pages? I like the controller. It keeps things seperate. I had a thought about this during chapter 11 One thing I notice was the controller and methods in a class. I found it interesting that the controller is mostly just passing data back and forth bewteen the controller. And if a model needs to make a change the controller pass in info to the class and the method of that class makes the chnage. I always was thinking that the controller did all the moving and changing. EFRepository has a save function and delete function. [HttpPost] public IActionResult Delete(int productId) { Product deletedProduct = repository.DeleteProduct(productId); //function in the EFrepostitory if (deletedProduct != null) { TempData["message"] = $"{deletedProduct.Name} was deleted"; } return RedirectToAction("Index"); } It's a function in a controller calling another function outsides of its domain. It's just passing information. This makes a lot more sense to me after this chapter. Contrllers move things. My question: When do you make the line of what the controller to do? Am I correct in what I'm thinking here?
