# 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
