How to programmatically set COM+ Component -> Transactions to Not Supported? - windows

Question

I am looking for a solution to programmatically modify Com+ Component Property -> Transaction Support to “Not Supported”
The manual steps are the following:
Open Component Services dialog (comexp.msc)
Expand Component Services -> Computers -> My Computer
Find and expand COM+ QC Dead Letter Queue Listener
Expand folder Components inside the opened component
Find component QC.DLQListener and open context menu for this component and select properties
On the Properties screen, select “Transactions” tab and set Transactions Support to Not Supported
Click “OK” to Save the changes

After I spent several hours on this problem, I've finally got a solution on C#.
I've got a huge insight from the following articles:
Changin the transaction atribute using COMAdminCatalog
Retrieve settings from COM+ components via C#
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using COMAdmin;
namespace SetComPlusTransactionsToNotRequired
{
class Program
{
static void Main(string[] args)
{
COMAdminCatalog catalog;
COMAdminCatalogCollection applications;
// Get the catalog
catalog = new COMAdminCatalog();
// Get the list of all COM+ applications contained within this catalog
applications = (COMAdminCatalogCollection)catalog.GetCollection("Applications");
applications.Populate();
foreach (COMAdminCatalogObject application in applications)
{
if (application.get_Value("Name") == "COM+ QC Dead Letter Queue Listener")
{
COMAdminCatalogCollection components;
components = (COMAdminCatalogCollection)applications.GetCollection("Components", application.Key);
components.Populate();
foreach (COMAdminCatalogObject component in components)
{
Console.WriteLine("Component: " + component.Name);
component.set_Value("Transaction", COMAdminTransactionOptions.COMAdminTransactionNone);
}
components.SaveChanges();
}
}
}
}
}
