导入目标文件以扩展 VS2017 中的构建目标

Question

我正在尝试使用 VS2017 扩展构建功能。我已将以下代码添加到 proj 文件的底部，就在 </Project> 标记之前：

  <Target Name="PrintA" BeforeTargets="Build">
    <Message Text="AAAAAAAAAAAAAa" Importance="high" />
  </Target>

按预期工作。现在我想创建单独的目标文件 - build.targets 并在那里添加构建逻辑。因此，我使用以下代码在解决方案根文件夹中创建了 build.targets 文件：

<?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <Target Name="PrintB" BeforeTargets="Build">
    <Message Text="BBBBBBBBBBBBBBBBBBBBB" Importance="high"/>
  </Target>
</Project>

然后也将导入添加到项目文件中：

然后我构建项目，打印 AAAAAA 而 BBBBB 没有。我想念什么？

更新：这是构建日志（我无法粘贴完整日志，我认为只有此信息相关）：

请注意，VS 2017 中的经典项目系统不会在构建期间重新加载导入的文件，即使它们发生变化。您至少需要关闭并重新打开解决方案才能使其正常工作。

对于 VS 2017 15.3+ 中的 "SDK-style" 项目（.NET Standard/Core、ASP.NET 核心），这由新项目系统 (GitHub issue) 处理。
