You can take advantages of Entityframework, this will be handle automatically. using (var context = new YourContext()) { Employer _employer= employee; // get your employee object _employer.Clients = clients // get clients list context.employers.add(_employer); context.SaveChanges(); } make sure you have define relationship in modelbuilder.

you don't need to do anything manytomany table itself , you can use navigation property of either of the table for add employers.clients= new List { new Client(){ id= "" ,Name= "" ; }} //for update Client c= db.Clients.Find(id); c.Name= "modifiedName" ; db.employers.Clients.Attach(c); db.Entry(c).State= EntityState.Modified.
