LINQ to SQL : Executing DML SQL Query
INSERT/DELETE/UPDATE can be performed in LINQ to SQL through normal T-SQL DML queries,
static void Main(string args)
NorthwindDBDataContext db = new NorthwindDBDataContext();
var query = db.ExecuteCommand("YOUR DML Query", "Your Parameter");
Are you feeling comfortable? Hold on, please try to avoid this as you have better object model approach.
