namespace ExtendedProperties_Testing
{
    class Program
    {
        static void Main(string[] args)
        {
            // The package is one of the SSIS samples.
            string mySample = @"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx";
            // Create the application, and load the sample.
            Application app = new Application();
            Package pkg = app.LoadPackage(mySample, null);

            // Get the Extended properties collection from the package.
            ExtendedProperties myExtProps = pkg.ExtendedProperties;
            
            // Give the count of the number of extended properties.
            int numProps = myExtProps.Count;
            Console.WriteLine("Current number of extended properties: {0}", numProps);
            // Remove an extended property.
            myExtProps.Remove("{A56842E2-11C1-487E-B670-33F25B534146}");
            // Give the new count of the number of extended properties.
            numProps = myExtProps.Count;
            Console.WriteLine("New number of extended properties: {0}", numProps);
            Console.WriteLine();
        }
    }
}

Imports System
Imports System.Collections.Generic
Imports System.Text
Imports Microsoft.SqlServer.Dts.Runtime
 
Namespace ExtendedProperties_Testing
    Class Program
        Shared  Sub Main(ByVal args() As String)
            ' The package is one of the SSIS samples.
            Dim mySample As String =  "C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx" 
            ' Create the application, and load the sample.
            Dim app As Application =  New Application() 
            Dim pkg As Package =  app.LoadPackage(mySample,Nothing) 
 
            ' Get the extended properties collection from the package.
            Dim myExtProps As ExtendedProperties =  pkg.ExtendedProperties 
 
            ' Give the count of the number of extended properties.
            Dim numProps As Integer =  myExtProps.Count 
            Console.WriteLine("Current number of extended properties: {0}", numProps)
            ' Remove an extended property.
            myExtProps.Remove("{A56842E2-11C1-487E-B670-33F25B534146}")
            ' Give the new count of the number of extended properties.
            numProps = myExtProps.Count
            Console.WriteLine("New number of extended properties: {0}", numProps)
            Console.WriteLine()
        End Sub
    End Class
End Namespace

Sample Output:

Current number of extended properties: 7

New number of extended properties: 6
