Error BE0042: You must specify at least one documentation source in the form of an assembly or a Visual Studio solution/project file

Cause

This error occurs if there are no assembly documentation sources or Visual Studio solution/project documentation sources that contain a useable assembly for reference information.

Solution

Check the following conditions which can cause this error:

  • You need to include at least one assembly or Visual Studio solution/project file in the help file project as a documentation source. Add the assembly, solution, or project to the Documentation Sources project node in the Project Explorer window.
  • If you are trying to build a help file based solely on additional or conceptual content, add the Additional Content Only Plug-In to the project via the PlugInConfigurations project property.
  • If the plug-in is included in the project, make sure that it is enabled by checking the box next to it in the plug-in configuration dialog box.
