Used cached entity for comparison

[bzuillsmith]

I can sometimes cache the unchanged state of an entity from the db. I tried attaching it to the context just before UpdateChanges but GraphDiff still queries the db. How would I make GraphDiff use the attached version instead of requerying it from the db?

Hi bzuillsmith

You can pass the persisted entity from the db to Merge method in GraphDiffer.cs file.

See the highlighted section in the below image. If you pass in the persisted object which is attached to context then GraphDiff shouldn't query again.

Indeed. Except that GraphDiffer is internal. So it would require modifying some other files as well. I may put the effort into a pull request if it seems like a reasonable solution to @refactorthis
