The project system could not create a project directory.

The project system will attempt to create all output directories as soon as the project is opened. The following is a list of the output directories created by the project system:

projectfolder\obj\configname

A temporary configuration-specific output directory.

projectfolder\obj\configname\temp

Working area used by the compiler.

projectfolder\obj\configname\temppe

Temporary assemblies used by designers at design-time are created here.

outputdir

The directory specified by the Output Path property. See Build Page, Project Designer (C#) for more information.

The most common reason for failing to create one of the directories under the obj folder is exceeding the MAX_PATH limit for directory names.

Less common reasons will include permission denied and out of disk space.

To correct this error

• If the path is too long, change the project location or shorten the name of the project configuration.

  The build process will fail if this error occurs.
