I don't have any experience with it I also keep wanting to try it it out. However the examples in the docs make it pretty clear how to accomplish those things, you have events that trigger a cshtml rerender to update the dom with c# code.

The example on the main page increments a counter using the @onclick event of a button, the @ denotes a server event.

If you ever used webforms back in the day it has some similarities.
