Creates an Azure Service Bus Subscription.

Note: This example requires Chilkat v9.5.0.65 or greater.

Go

    // This requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // Make the initial connection.
    // A single REST object, once connected, can be used for many Azure Service Bus REST API calls.
    // The auto-reconnect indicates that if the already-established HTTPS connection is closed,
    // then it will be automatically re-established as needed.

    // The code above this comment could be placed inside a function/subroutine within the application
