The EF framework has many levels and versions by now. When you're using an ObjectContext you can use ApplyCurrentValues :

T ApplyCurrentValues<T>(string entitySetName, T currentEntity)

+1 This is correct answer but it will work only for scalar and complex properties. It will not handle navigation properties and EF has [no automatic solution for that](http://stackoverflow.com/questions/3635071/update-relationships-when-saving-changes-of-ef4-poco-objects/3635326#3635326). – Ladislav Mrnka Jan 07 '12 at 22:49
