azure - What is the difference between Worker Role and Worker Role with Service Bus Queue -

what difference between these 2 implementations, can tell 1 use under scenario?

also pros , cons if there any? in advance.

there isn't difference between two. worker role service bus queue vs project template adds service bus dependencies , configures empty message handling function , adds code ready set own connection string etc.
if planning on implementing worker role reads queue save little typing time. if prefer can create basic worker role project , add queue handling logic it, achieve same thing.
