DbUpdateConcurrencyException DbUpdateConcurrencyException DbUpdateConcurrencyException Class


Exception thrown by DbContext when it was expected that SaveChanges for an entity would result in a database update but in fact no rows in the database were affected. This usually indicates that the database has been concurrently updated such that a concurrency token that was expected to match did not actually match. Note that state entries referenced by this exception are not serialized due to security and accesses to the state entries after serialization will return null.
