Question

当我尝试在.NETStandard库的自定义构建目标中使用$(TargetFrameworkSDKToolsDirectory)或$(SDKToolsPath)等msbuild属性时，这些属性为空/未定义。然而，使用完全相同的.NET 4.6.2程序集构建目标可以正常工作。是否有.targets文件我需要手动包含.NETStandard或我还能缺少什么？

导入$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props没有帮助。我正在使用Visual Studio 2017社区。

* .csproj for .NETStandard lib：

<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
        <TargetFramework>netstandard1.4</TargetFramework>
        <RootNamespace>MyNamespace</RootNamespace>
        <AllowUnsafeBlocks>True</AllowUnsafeBlocks>
    </PropertyGroup>
    <!--
    ItemGroups for files and references
    -->
    <Target Name="PropsTest" BeforeTargets="CoreCompile">
        <!-- Prints: "Path: " -->
        <Message Text="Path: $(TargetFrameworkSDKToolsDirectory)" Importance="high" />
    </Target>
</Project>

* .csproj for .NET 4.6.2 app：

Answer 1

对于.NET 4.6.2库，TargetFrameworkSDKToolsDirectory属性由Microsoft.NETFramework.CurrentVersion.props设置。

使用$（SDK35ToolsPath）或$（SDK40ToolsPath）进行设置。

SDK40ToolsPath属性在.NET标准库构建中可用，即使TargetFrameworkSDKToolsDirectory不是。

对于.NETStandard lib项目，MSBuild属性为空
