This looks like a known issue sourced from MSDN forums - you just need to update your Microsoft.VisualStudio.Tools.Office.targets file to point to version 11.0.0.0 instead of version 10.0.0.0.

Updating MSBuild Targets File

For those who encounter this problem, go to C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\OfficeTools and open the Microsoft.VisualStudio.Tools.Office.targets file.

Replace all 10.0.0.0 with 11.0.0.0.
