Description
In the new stored procedure mapping support, the logic to count parameters for the purpose of propagating sproc output variables incorrectly assumed all commands in the batch use a sproc. This causes us to propagate the wrong database-generated value into the wrong entity property.
Customer impact
When mixing both stored procedure and non-stored procedure updates in the same SaveChanges batch, database-generated values may cause an exception, or even get assigned to the wrong entity property (bad data).
How found
Customer reported on 7.0
Regression
No.
Testing
Added a test for the affected scenario.
Risk
Low; the fix is quite trivial, and a quirk was added to revert back to older behavior.
