How to determine the GUID of the root namespace container page?

Jul 22, 2014 at 6:55 PM
In the introduction section, I want to create a short table of contents with description of major documentation sections. It's trivial for content topics, but how do I reference the root page of the API documentation? I assume the topic has a GUID, but I can't figure out where it is defined.

I think I figured this out. Not sure if this is a preferred way, but to reference the auto-generated topic used as the root namespace container, I used the following

<codeEntityReference linkText="API reference">R:Project_HelpFileName</codeEntityReference>

where HelpFileName is the value in the Help file name field in the Sandcastle project properties (Help File tab), and API reference is the text that appears instead of the default. Again, can't say that this is a recommended approach, but it seems to work.

Yes, that is the correct approach. The help file name is included to keep the root topic ID unique which is a requirement for Help Viewer output.
