Answer 1

You can't insert into 2 tables using 1 sql Insert statement.

However, you can use following options

1. Using Entity Framework , you can create the entities which are linked together. It's much more simpler to perform CRUD (Create, Read, Update & Delete) operation on EF entities as conceptual model is set of classes.

2. Create a stored procedure and insert into 2 tables in the stored procedure.
