Answer 1

if

      using(var db = new MyDbContext())
            {
               await db.Database.ExecuteSqlCommandAsync(@"TRUNCATE TABLE MyTable"););
            }

causes

Cannot truncate table 'MyTable' because it is being referenced by a FOREIGN KEY constraint.

I use this :

      using(var db = new MyDbContext())
               {
                   await db.Database.ExecuteSqlCommandAsync(@"DELETE FROM MyTable WHERE ID != -1");
               }
