如何在MVC5（Ajax / jQuery）中动态更新模型

Question

I have a simple ASP.net MVC5 website with Code-first EF. I would like to learn how to automatically update/refresh the view-models so that the user sees updated information.

The website is a simple auction site and I would like the current bid amount to automatically refresh in a user's view. The refreshing could be either server-pushed or client-polled; I don't mind which.

My current understanding is that this can be achieved using an Ajax toolkit or using jQuery. But I have not used these technologies before and docs/tutorials for this scenario seem to be lacking. I would very much appreciate a couple of pointers as to where I can start reading relevant material about the options and how to go about this seemingly simple task.

A short code sample would also be of great benefit.

For a client-polled solution, you can use MVC "Partial views" and jQuery.
