How to connect an application (c#) to MongoDB?

Question

MongoDB

I was asked a coursework .. I have an Encyclopedia application. there I have various biographies of characters, objects, and so on. I need to somehow connect all this to mongoDB, but I don’t understand how. it is necessary that these characters, their biographies, etc. be stored in this mongoDB. also so that when I open the application, the selection should go through, how to do this?
also, the list of articles should be loaded, when you select an article, it should be found in the database and opened. how can i do all this? what to study? please help, because the coursework will be handed over in 3 days: D it is desirable to explain everything in an understandable language
