Saving changes/updating existing object in dataset with Entity FrameWork and not have to set each property individually?
You can attach the existing product and set its state as Modified If you are using DbContext API context.Products. Attach(product); context. Entry(product).
State = EntityState. Modified; context.SaveChanges() For ObjectContext context.Products. Attach(product); context.
ObjectStateManager. ChangeObjectState(product, EntityState. Modified); context.SaveChanges().

Does not contain a definition for "Entry". Do I need to reference something? Already using System.Data.
Objects; What else? Pressing ctrl + . Gives nothing for Entry.
– LaserBeak Oct 4 at 2:18 @LaserBeak It looks like you are using ObjectContext. See my updated answer. – Eranga Oct 4 at 3:51.
We do this by adding the mutations we want to a mutation pool, then, periodically as the pool hits a certain size, we flush all the writes to the datastore with a single call instead of individually. This has the advantage of making our map() call as fast as possible, since all we’re really doing is making a list of operations to perform all at once when the system is good and ready. It looks almost exactly the same.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
