Context-sensitive HTML Help for .NET application

[Peggy McClure]

I'm new to creating HTML Help, and not sure how to accomplish
context-sensitive help for a .NET application.

I'm using RoboHelp X5 to create the HTML Help .chm  file with (ideally)
window-level context sensitivity. The application I'm documenting was
created using CSharp NET, (C# .NET?) and the developer tells me it does not
use .h files. He is looking for keywords to implement the context-sensitive
help, which they've used in the past with a .chm file, rather than topic
IDs.

I've searched the TECHWR-L archives and other sources, but haven't found
anything specifically for what kind of file to deliver for the
context-sensitive help mapping, and how to create the keywords. (As far as I
can tell, I should be able to do this with RoboHelp X5).

Are these keywords the same as the topic keywords or index keywords? What
type of file does a .NET application need instead of the .h file? As far as
I can tell from searching the web, the RoboHelp X5 supports .NET, and I
should be able to do this with RoboHelp X5.

I'm missing a piece of the puzzle (or maybe a few) - any help is greatly
appreciated.

Regards
