TransactionOptions options = new TransactionOptions();
            options.IsolationLevel = System.Transactions.IsolationLevel.ReadCommitted;
            options.Timeout = new TimeSpan(0, 10, 0); 
            using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required, options))
            { 	

	        // Method 1 which has DB connnection am opening and coling the connection properly
		// Method 2	 which has DB connnection am opening and coling the connection properly
		// Method 3  which has DB connnection am opening and coling the connection properly		
		
             scope.Complete();

DAL Layer :</div> <div></div> <div>

public class EmpDB  : DbContext
    {
        public EmpDB()
        {
        }

        public EmpDB(DbContextOptions<EmpDB> options)
            : base(options)
        {
        }

        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        {
            if (!optionsBuilder.IsConfigured)
            {
                optionsBuilder.UseSqlServer(//ConnectionString);
            }
        }


public int GetEmpId(string EmpEmail)
        {
            using (EmpDB empDB = new EmpDB())
            {
                using (var dbCommand = empDB.Database.GetDbConnection().CreateCommand())
                {
                    // proc call with parameters

                    if (dbCommand.Connection.State != ConnectionState.Open)
                    {
                        dbCommand.Connection.Open();
                    }
                    int EmpId = (int)dbCommand.ExecuteScalar();
                     
                    dbCommand.Connection.Close(); 
                    return EmpId 
                }
      }
  }
