Question

I have a EF entity retrieved and bound to some UI controls using Unit of Work

public RowItem MyItem { get; set; }
using ( var ctx = new MyContext() )
    MyItem = ctx.MyEntity.Single( x =>  /// parms };


at a later time, the updates are saved on some user action

Question – how can i use the existing entity MyItem and keep it simple along the lines of

using ( var ctx = new MyContext() )
       MyItem.UpdateUsingContext(ctx);

Answer 1

Well, saving an object in EF is simple:

context.SaveChanges();

This saves all updated/new/deleted object in context.

If your objects were not created in this particular instance of context you should attach them before saving:

context.Attach(entity);
context.SaveChange();
