I am attempting to follow the code snippets on the link shown below and have been able to retrieve and create new database records.

The issue is that trying this code snippet below doesn't actually update the database:

product.ProductName = "Edited product";
product.Price = 15;
context.SaveChanges();

Previously with the Microsoft/Oracle ADO .NET provider I would do something like this:

product.ProductName = "Edited product";

product.Price = 15;

context.Entry(product).State = EntityState.Modified;

context.SaveChanges();
