Marty Wasznicky has posted a compiled BizTalk 2004 Help File (.chm) check it out in his blog (11 Mb)
The most interesting stuff is that it can be indexed using MSN Desktop Search (as any other .chm file)…. that means querying BizTalk Documentation from the Windows Taskbar. Cool, since I’ve tried to index the Visual Studio Combined Help files without success 🙁
