Warning BE0003: Sandcastle shared content for the '[langId]' language could not be found. Using 'en-US, English (US)' defaults.
This warning indicates that a set of Sandcastle shared content files do not exist for the selected language.
If a set of language resource files do not exist, the US-English defaults are used. If you need resources to appear in the language selected in the project file, you will need to create a set of content files for the selected language. See the Localizing Language Resource Files topic for details.
Note
While you can send translations of the help file builder shared content files to the Sandcastle Help File Builder project, do not send any translated Sandcastle presentation style files as they are not part of the help file builder and will not be included as part of it.
