VS2012 $(exists) only accepts scalar values

Question

Okay, this is more of a build error than a programming error. I have never had much reason to get my hands dirty with builds, so this error is baffling me.

I have tried

Answer 1

I got the same error in VS2013, but only when I try to rebuild the project. Below how I solve the problem in my conditions, I hope that is also useful to other people.

Configuration:

• I have my typescript files in separate projects in the solution.
• Those projects were migrate for VS 2012.

Cause: when I click on the error in Microsoft.Web.Publishing.targets files I discovered that the project was using the VS2012 version of those files. That is the projects where only partially migrated form VS2012 to VS2013.

Solution: Open the typescript project (first unload project) Search for:

      <PropertyGroup>
        <VisualStudioVersion Condition="'$(VisualStudioVersion)' == ''">12.0</VisualStudioVersion>
        <VSToolsPath Condition="'$(VSToolsPath)' == ''">$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)</VSToolsPath>
      </PropertyGroup>

• Comment the line VSToolsPath
• Save and close the file

• Reload the project You can see a migration screen from visual studio notifying you that the project was upgrade.

  rebuild the project, now should work
