Hi Ahmet,
I tested this here and it works fine for me.
I added your program to an x86 managed class library project and added the SQL(DBMAN=ADO) and ilsmartlinkage directives to it.
I then created a C# cnsole app, added a reference to my COBOL project and I am able to code the following which shows in Intellisense also.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
CoreBanking.Transactions.ExecuteTransaction cobprog = new CoreBanking.Transactions.ExecuteTransaction();
TansactionRecord tr = new TansactionRecord();
tr.CreditAccount = 123;
}
}
}
