EF Core by Patrik

Disconnected Scenario

Make EF Core update only the updated properties by turning the disconnected scenario to connected.

public void SaveBook(Book book)
    // Here, 'book' is the book with the changed Title.
    using(var context = new TestContext())
        var dbBook = context.Books.Find(book.ID);

        // Copy book's property values to dbBook.


There may be good reasons to prefer the latter method above the former.
