Please note that as of October 24, 2014, the Nokia Developer Wiki will no longer be accepting user contributions, including new entries, edits and comments, as we begin transitioning to our new home, in the Windows Phone Development Wiki.

Cs help compiler
Context Sensitive Help (CS Help) provides users with the specific help topic for the context in which they have a problem. CS Help files are generated using the CS Help compiler, which replaces the Aleppo help authoring tool used in releases prior to and including v5.
The CS Help compiler builds help files from the command line, using information defined in a project file, rtf source file or files, and an optional customisation file. The compiler also generates a C++ header file containing literal descriptors for each context—which can be used to provide a link to the appropriate help topic from an application.
