Sandcastle Help File BuilderBE0068: Incompatible Visual Studio project file format

Error BE0068: Incompatible Visual Studio project file format. [error]

Cause

An attempt was made to use a Visual Studio project as a documentation source that has an incompatible format. C++ projects created with Visual Studio 2008 and earlier do not use an MSBuild-based format and cannot be parsed. Visual Studio 2010 projects use MSBuild 4.0 which defines some new elements and attributes not recognized by the MSBuid 3.5 engine used by the help file builder to load project files. If a project is encountered that uses these new elements, it cannot be loaded.

Solution

Add the assembly and XML comments file created by the Visual Studio project to the help file builder project as documentation sources rather than the project file that contains them. Likewise, add any required references from the Visual Studio project to the help file builder project's References project node.
