You are implementing an Entity Framework application. A method retrieves and modifies Entity Framework entities. You need to persist all updates to the data source.

What should you do?

The ObjectContext's SaveChanges method writes changes to the data source.

The ObjectContext's Refresh method updates an object in the object context with data from the data source. Setting the RefreshMode to StoreWins ensures that data source values overwrite client-side changes. This method does not persist changes to the database.
