Controller
The SchoolContext _context tells the Controller and View what the database looks like and all the information in it. Index lets us view all the Delinquents information in general using the ToListAsync() method which puts all the books into a table. Create first gives us the Create view and then once the information is given, it checks that the model is correct and if so, adds it to the database and takes you back to the Index. It also uses SaveChangesAsync to save the information Delete deletes the given selection after checking that it exists. It first uses FirstorDefaultAsync which returns the first element of the sequence asynchronously. And uses the Lambda method to briefly show the anonymous method. And then saves it to the database after deleting the selected object. Details lets us view more detailed information about the given object. It also uses the FirstorDefaultAsync and Lambda methods. Edit lets us modify the given object. It uses the FirstorDefaultAsync and Lambda methods. It also has a post method which then saves everything that was changed.
