I'm working on an ASP.NET MVC project, I use Entity
Framework [ Database First ], I created a data
model
depend on SQL server database, I created
a Table in the database and I updated the data model from the database, and when I try to add a record to the new table I created (this table doesn't have a PK) I
got an error, when I search about the error I Understood that in Entity Framework need to have a PK for Entity.
So I ASK if I can set a Primary Key
for an Entity
without affect database, or any other solution to solve this problem and massive thanks in
advance.
