[C#]

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;

namespace TaskInfos_Item
{
    class Program
    {
        static void Main(string[] args)
        {
            Application app = new Application();
            TaskInfos tInfos = app.TaskInfos;

            if (tInfos.Contains("Data Flow Task"))
            Console.WriteLine("The application contains the Data Flow Task");
        }
    }
}

Imports System
Imports System.Collections.Generic
Imports System.Text
Imports Microsoft.SqlServer.Dts.Runtime
 
Namespace TaskInfos_Item
    Class Program
        Shared  Sub Main(ByVal args() As String)
            Dim app As Application =  New Application() 
            Dim tInfos As TaskInfos =  app.TaskInfos 
 
            If tInfos.Contains("Data Flow Task") Then
            Console.WriteLine("The application contains the Data Flow Task")
            End If
        End Sub
    End Class
End Namespace

Sample Output:

The application contains the Data Flow Task
