BUG: DbUpdateConcurrencyException when updating and inserting multiple records

4119029Oct 25 2019 — edited Dec 7 2019

When updating and adding multiple rows I am getting a DbConcurrency exception. Note no table has more than 10 rows in it. This only occurs when multiple rows are updated AND inserted within the same SaveChanges() operation.

Microsoft.EntityFrameworkCore.DbUpdateConcurrencyException: 'Database operation expected to affect 1 row(s) but actually affected 2858 row(s).

The sample code is located here: https://github.com/inferno31/oefc-concurrency-issue
