How to setting a model with table don't have any primary key column?

[ndphuong]

The EFCore throw exception: The entity type XXX requires a primary key to be defined
But our table don't have any primary key column

How to avoid this ?

@ndphuong EF Core requires all mapped entity types to have a primary key defined. This is needed so that different entity instances can be uniquely identified for tracking.

Can you provide some details of what you are trying to do so we might be able to give some advice on how to approach it.

@ajcvickers
We are using EFCore to try access a read-only database
Some table don't have any primary key column so EF throws exception
