CM Messaging SDK Documentation shouldn't be a .chm help file AND...
The docs that exist for the CM Messaging (note, the messaging SDK is not a part of the larger CM SDK docs here https://msdn.microsoft.com/en-us/library/hh442686(v=cmsdk.16).aspx) is currently a .chm Help file, which is lovably nostalgic.
However it doesn't do justice to the power of the SDK. For instance, Discovery and hardware inventory are barely covered in the SDK docs. I'm troubleshooting an issue now with the Messaging SDK in which a fake CM Client appears with Windows 6.2 NT Workstation, even though it is a fully patched Win10 machine. Weird stuff.
Anyway, it would be great if the docs were not a .chm file, but redone in the lovely style we have here: https://msdn.microsoft.com/en-us/library/hh442686(v=cmsdk.16).aspx
The latest iteration of the docs for the messaging SDK are here: https://msdn.microsoft.com/en-us/library/mt744369.aspx
Migrating to docs.microsoft.com and further fleshing out the documentation here is something that’s on our radar for the future.
