BE0068: 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.

  • MSBuild projects in the version 1.0 and 2.0 format cannot be parsed. These must be upgraded to the newer format used by MSBuild 4.0 and later.

  • C++ projects created with Visual Studio 2008 and earlier do not use an MSBuild-based format and cannot be parsed.

  • Future versions of Visual Studio may introduce new MSBuild elements and attributes not recognized by the MSBuild engine used by the help file builder to load project files resulting in this error.

Solution

As a last resort, 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.

If the project is using a newer MSBuild file format, please open an issue in the Sandcastle Help File Builder project and request support for the new project file format.
