Property Value

Remarks

For keys with store-generated properties (e.g. mapping to Identity columns), the return value will be false if any of the store-generated properties have the CLR default value.

For keys without any store-generated properties, the return value will always be true since any value is considered a valid key value.

See EF Core change tracking for more information and examples.
