Performing an update operation is an extremely simple operation. You need a reference to an existing object in the database. Once you have it, just update its properties and invoke the well-known SaveChanges method.
| C# |
 Copy Code |

Customer customerToUpdate = dbContext.Customers.First();
customerToUpdate.Fax = "[newFax]";
dbContext.SaveChanges(); |
| VB.NET |
Copy Code |

Dim customerToUpdate As Customer = dbContext.Customers.First()
customerToUpdate.Fax = "[newFax]"
dbContext.SaveChanges() |
