Dim applicationName As String = "MyApplicationName"
Dim subscriptionClassName As String = "MySubscriptionClassName"
Dim subscriptionFieldName As String = "MySubscriptionFieldName"

'Create an NSInstance object.
Dim myInstance As New NSInstance(instanceName)

'Create an NSApplication object.
Dim myApplication As New NSApplication(myInstance, applicationName)

'Create a Subscription object.
Dim mySubscription As _
    New Subscription(myApplication, subscriptionClassName)

'Use the Item property to set a field value.
mySubscription(subscriptionFieldName) = "MyValue"

string instanceName = "MyInstanceName";
string applicationName = "MyApplicationName";
string subscriptionClassName = "MySubscriptionClassName";
string subscriptionFieldName = "MySubscriptionFieldName";

//Create an NSInstance object.
NSInstance myInstance = new NSInstance(instanceName);

//Create an NSApplication object.
NSApplication myApplication = 
    new NSApplication(myInstance, applicationName);

//Create a Subscription object.
Subscription mySubscription = 
    new Subscription(myApplication, subscriptionClassName);

//Use the Item property to set a field value.
mySubscription[subscriptionFieldName] = "MyFieldValue";
