The property 'Id' is part of the object's key information and cannot be modified

Question

i\'m using Entity Framework 4.0 and having a silly problem that i can\'t figure out.

I have two tables:

1. Contact: Id (primary key), Value, ContactTypeId

Answer 1

Just hoping this helps someone else, after struggling for hours with this because i knew i wasnt updating the PK and i definitely had a PK. I had the PK value databound to a menu bar to show the current PK value and this was causing the issue.
