I used these in the web-casts below and have had numerous requests for them. There is a correlation sample (thanks Eric), and here is the SOAP headers example (thanks team), and a SOAP fault example (thanks team). I packaged these in a bit of a rush, so post if you have issues with running/understanding them...
There are more samples coming from the product team in the next month or so, stay tuned.
Also the decks used in the web-casts except one (which is coming) are zipped and uploaded here.
Finally, The installation guide (everyone reads that when installing the product right?) is in \Program Files\Microsoft BizTalk Server 2004\Documentation\Installation Guide.htm. It includes links to a set of hotfixes to windows/sql that are required for BizTalk Server 2004 and are not installed by our default installation program for security reasons. Please make sure you have all the right ones for your OS.
I'll be a little slow on my blog in the next few weeks as I make my way to launch events in California, Belgium and the UK.
