Simple. You don't.

If there's no primary key, Entity Framework can't use the table. EF MUST have a way to uniquely identify every record in the table, and that means having primary keys.

Really, you don't even want to work with "tables" that don't have keys without some ORM. It can be an elephanting nightmare to deal with.

Do not attempt to "work around" a condition like this. Just fix the data model and add keys to the tables that don't have them.
