My recommendation would be to take one of the SDK sample adapters and debug
it until you understand the basic process flow. Adapters generally break
down into three parts; the design-time component you see in BizTalk
Explorer, a receive component and a transmit component. You'll see that the
samples use a set of base classes which implement a lot of the
BizTalk-specific functionality. At this stage you can safely ignore these
classes and concentrate on the actual implementation which means that you
really just need to understand what the C# code is doing rather than having
to fully understand BizTalk at this stage.
When you have figured out how the sample adapter works you'll see that there
are really only a couple of places that you need to modify to talk directly
to TIBCO, so take the sample adapter projects and start modifying them to
suit your needs. Plan on refactoring your first attempt at least once and
you should end up with a working adapter.
To begin with, forget about the details and concentrate on getting the basic
receive and transmit code running. You can hardcode all the bindings to
start with and forget about implementing the 'add generated items' stuff
until later. I would suggest creating the code to connect to TIBCO in a
regular VS.NET project and get that all working first. Then you can just
build it into the adapter.
It isn't all that straightforward when you first look at it but after you
understand what the code is doing, things get a lot easier.
