"Overriding value generation" code sample doesn't work for explicitly setting values

[JohnH-Work]

Type of issue

Code doesn't work

Description

The "Overriding value generation" code sample doesn't appear to work correctly. When using ValueGeneratedOnAddOrUpdate, it won't save an explicit value. I had to use ValueGeneratedOnAdd instead to get it to auto-generate a value when none supplied and still save explicitly set property values.

See also this guide, which explains how ValueGeneratedOnAddOrUpdate and ValueGeneratedOnAdd behave differently when setting explict values: https://www.learnentityframeworkcore.com/model/generated-value
