Visual Studio 2015的全球VC ++目录？

Question

我试过文件C：\ Users \ DrHanner \ AppData \ Local \ Microsoft \ MSBuild \ v4.0：

<?xml version="1.0" encoding="utf-8"?> 
<Project DefaultTargets="Build" ToolsVersion="12.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <ImportGroup Label="PropertySheets">
    <IncludePath>D:\!\c++\include;$(IncludePath)</IncludePath>
    <LibraryPath>D:\!\c++\libs;$(LibraryPath)</LibraryPath>
  </ImportGroup>
  <PropertyGroup Label="UserMacros" />
  <PropertyGroup />
  <ItemDefinitionGroup />
  <ItemGroup />
</Project>

和

  <PropertyGroup Label="UserMacros" />
    <IncludePath>D:\!\c++\include;$(IncludePath)</IncludePath>
    <LibraryPath>D:\!\c++\libs;$(LibraryPath)</LibraryPath>
  <PropertyGroup />

错误消息是元素importgroup下的元素includepath无法识别。

也不起作用， 和其他窗口 - ＆gt; propertyManager不存在。

也许是因为我有试用版......
