I have create a new project in win8 CP, then compare the vcxproj file I found the new one has add something:

<Midl Include="GeometricSource.idl">
      <MetadataFileName Condition="'$(Configuration)|$(Platform)'=='Debug|Win32'">
      </MetadataFileName>
      <MetadataFileName Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">
      </MetadataFileName>
      <MetadataFileName Condition="'$(Configuration)|$(Platform)'=='Debug|ARM'">
      </MetadataFileName>
      <MetadataFileName Condition="'$(Configuration)|$(Platform)'=='Release|ARM'">
      </MetadataFileName>
      <MetadataFileName Condition="'$(Configuration)|$(Platform)'=='Debug|x64'">
      </MetadataFileName>
      <MetadataFileName Condition="'$(Configuration)|$(Platform)'=='Release|x64'">
      </MetadataFileName>
      <AdditionalMetadataDirectories Condition="'$(Configuration)|$(Platform)'=='Debug|Win32'">$(WindowsSDK_MetadataPath)</AdditionalMetadataDirectories>
      <AdditionalMetadataDirectories Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">$(WindowsSDK_MetadataPath)</AdditionalMetadataDirectories>
      <AdditionalMetadataDirectories Condition="'$(Configuration)|$(Platform)'=='Debug|ARM'">$(WindowsSDK_MetadataPath)</AdditionalMetadataDirectories>
      <AdditionalMetadataDirectories Condition="'$(Configuration)|$(Platform)'=='Release|ARM'">$(WindowsSDK_MetadataPath)</AdditionalMetadataDirectories>
      <AdditionalMetadataDirectories Condition="'$(Configuration)|$(Platform)'=='Debug|x64'">$(WindowsSDK_MetadataPath)</AdditionalMetadataDirectories>
      <AdditionalMetadataDirectories Condition="'$(Configuration)|$(Platform)'=='Release|x64'">$(WindowsSDK_MetadataPath)</AdditionalMetadataDirectories>
      <EnableWindowsRuntime Condition="'$(Configuration)|$(Platform)'=='Debug|Win32'">true</EnableWindowsRuntime>
      <EnableWindowsRuntime Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">true</EnableWindowsRuntime>
      <EnableWindowsRuntime Condition="'$(Configuration)|$(Platform)'=='Debug|ARM'">true</EnableWindowsRuntime>
      <EnableWindowsRuntime Condition="'$(Configuration)|$(Platform)'=='Release|ARM'">true</EnableWindowsRuntime>
      <EnableWindowsRuntime Condition="'$(Configuration)|$(Platform)'=='Debug|x64'">true</EnableWindowsRuntime>
      <EnableWindowsRuntime Condition="'$(Configuration)|$(Platform)'=='Release|x64'">true</EnableWindowsRuntime>
      <HeaderFileName Condition="'$(Configuration)|$(Platform)'=='Debug|Win32'">%(Filename).h</HeaderFileName>
      <HeaderFileName Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">%(Filename).h</HeaderFileName>
      <HeaderFileName Condition="'$(Configuration)|$(Platform)'=='Debug|ARM'">%(Filename).h</HeaderFileName>
      <HeaderFileName Condition="'$(Configuration)|$(Platform)'=='Release|ARM'">%(Filename).h</HeaderFileName>
      <HeaderFileName Condition="'$(Configuration)|$(Platform)'=='Debug|x64'">%(Filename).h</HeaderFileName>
      <HeaderFileName Condition="'$(Configuration)|$(Platform)'=='Release|x64'">%(Filename).h</HeaderFileName>
    </Midl>

Add this into vcxproj file and then resolve the problem
