自定义 dll 集成到 HoloLens 项目中

Question

我有一个带有源代码的自定义库，可以成功编译并生成 .dll 文件。

问题：考虑到以下错误，将此 dll 包含在 HoloLens 项目中的最佳方法是什么？

我的做法

独立库的project.json文件如下：

{
  "dependencies": {
    "Microsoft.NETCore.UniversalWindowsPlatform": "5.1.0",
    "Newtonsoft.Json": "9.0.1"
  },
  "frameworks": {
    "uap10.0": {}
  },
  "runtimes": {
    "win10-arm": {},
    "win10-arm-aot": {},
    "win10-x86": {},
    "win10-x86-aot": {},
    "win10-x64": {},
    "win10-x64-aot": {}
  }
}

或者我也有机会将其添加为 NuGet 包，具体取决于：
- Microsoft.NETCore.UniversalWindowsPlatform (>= 5.2.2)
- Newtonsoft.Json (>= 9.0.1)
- Microsoft.EntityFrameworkCore.Tools（>=1.0.0-preview2-final）
- Microsoft.EntityFrameworkCore.Sqlite (>= 1.0.1)

然后我需要将这个库包含在另一个由 Unity for Hololens 制作的 VS2015 解决方案中。 Unity 自动构建的解决方案包含 3 个项目：1) Assembly-CSharp 包含一个 HoloToolkit 文件夹，2) Assembly-CSharp firstpass 和 3) Origami

我从 HoloToolkit for Unity 文件夹中获取了一个脚本并将其应用于 GameObject。当一个事件被触发时——它成功发生了——我想调用这个自定义库提供的一些函数来从同一个脚本中处理它，比如 GazeManager.cs。项目1)的project.json如下

{
  "dependencies": {
    "Microsoft.NETCore.UniversalWindowsPlatform": "5.0.0"
  },
  "frameworks": {
    "uap10.0": {}
  },
  "runtimes": {
    "win10-arm": {},
    "win10-arm-aot": {},
    "win10-x86": {},
    "win10-x86-aot": {},
    "win10-x64": {},
    "win10-x64-aot": {}
  }
}

我尝试了两种方式：

在GazeManager.cs中我在代码中添加了using MyLibrary并将其添加为ReferenceManager中的引用。该库得到正确识别，但随后只需声明一个变量，如 public MyLibrary objectInMyLibrary 就会从一个正确编译的程序切换到一个出现以下错误的程序：

The command ""C:\Users\Antonino\Documents\UnityToVS2015Projects\HoloAcademy101 - Origami\Origami\App\Unity\Tools\AssemblyConverter.exe" -platform=uap -lock="C:\Users\lakeb\Documents\UnityToVS2015Projects\HoloAcademy101 - Origami\Origami\App\Origami\project.lock.json" -bits=32 -configuration=Debug -removeDebuggableAttribute=False -path="." -path="..\Players\UAP\x86\Debug" "C:\Users\lakeb\Documents\UnityToVS2015Projects\HoloAcademy101 - Origami\Origami\App\Origami\Assembly-CSharp.dll" "C:\Users\lakeb\Documents\UnityToVS2015Projects\HoloAcademy101 - Origami\Origami\App\Origami\Assembly-CSharp-firstpass.dll" "C:\Users\lakeb\Documents\UnityToVS2015Projects\HoloAcademy101 - Origami\Origami\App\Origami\UnityEngine.dll" "C:\Users\lakeb\Documents\UnityToVS2015Projects\HoloAcademy101 - Origami\Origami\App\Origami\UnityEngine.UI.dll" "C:\Users\lakeb\Documents\UnityToVS2015Projects\HoloAcademy101 - Origami\Origami\App\Origami\UnityEngine.HoloLens.dll" "C:\Users\lakeb\Documents\UnityToVS2015Projects\HoloAcademy101 - Origami\Origami\App\Origami\UnityEngine.Networking.dll" "C:\Users\lakeb\Documents\UnityToVS2015Projects\HoloAcademy101 - Origami\Origami\App\Origami\UnityEngine.VR.dll"" exited with code 1.

[取消前面的步骤以再次编译 Origami] 我认为的第二种方法是通过在 project.json 文件
中插入行来添加它
"my.hololens.library": "version"

在这种情况下，我得到了以下错误

我不知道接下来会发生什么。有人说要制作一个可移植的库，我也尝试研究hereNETFramework、NETCore和NETStandard之间的关系，但似乎比预期的要复杂。

Answer 1

Unity 3d 不支持集成使用 .Net Core 框架的库。尝试将您的库创建为 .Net Framework 3.5 库并将其放入 Unity 项目的 Assets/Plugins 文件夹中。

Answer 2

您需要创建一个 UWP Library 项目并将您的代码移植到该项目并编译，删除错误将编译后的 dll 放在 assets 文件夹中如下所示更新 Inspector 属性

现在您可以在 #if !UNITY_EDITOR 块

下的统一脚本中访问此 dll
