问题
总结起来，Unity 和 Visual Studio 2017 都构建了项目，部署了项目，但是一旦打开应用程序，什么都没有出现，甚至没有出现 Unity 启动画面。然而，在 HoloLens 上做出绽放手势证明该应用程序是“打开的”和可关闭的，但仅此而已。
我们尝试了什么我们
的部署目标是运行最新操作系统的 HoloLens 1 (10.0.17763.380)。
我们在这里查看了提供的解决方案：
MRTK (V2) Need to update Hololens?
如下图所示：
注意：下图显示了 Visual Studio 2019，但我们使用 Visual Studio 2017 和 Visual Studio 2019 测试了这两种情况。
我们安装了 Windows 10 Insider Preview SDK（请原谅丹麦人）
并尝试遵循此处提供的解决方案： 无法使用 MRTK v2.0.0-RC1 构建
这似乎与问题的其他答案似乎相冲突。
然而，此解决方案尝试提供了另一个错误，称部署目标 (HoloLens 1) 必须运行 OS 10.0.18326，这是有道理的，因为据我们所知，此特定设备不存在此 OS。如前所述，我们在最新的操作系统 10.0.17763 上运行。
至于将 C# 语言更改为 7.2，我们遇到了麻烦，因为所有指南都说要从解决方案属性中的构建访问该语言，但我们无法找到此选项卡。当我们在 Visual Studio 层次结构中右键单击 projectname.sln 后尝试按“属性”时，会发生以下情况：
但是，我们希望我们可以更改语言设置，如下所示：
但正如您所看到的，没有“构建”选项卡，我们看到的内容看起来与我们建议的应该显示的内容有些相去甚远。
我们对 HoloLens 1 的期望
一个可以打开的工作 HoloLens 1 应用程序，就像 MRTK v2 Beta 版本一样。
实际发生
了什么
正如问题中提到的，应用程序被构建和部署，但它不仅充满了错误，而且在打开构建的应用程序时什么也没有出现。
统一错误可以在这里看到：
