Windows 10 个 IoT ARM (Raspberry Pi) System.Threading - 缺少引用

Question

我正在尝试为 Raspberry Pi 2 编译 UWP C# 解决方案。这里是 project.json:

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

问题是我正在引用（通过 dll，我无法通过对项目的正常引用添加它）到另一个项目，该项目使用 System.Threading 进行某些线程操作。这里是 project.json:

{
"version": "1.0.0-*",

"dependencies": {
  "ELMSDefinitionsCore": "1.0.0-*",
  "NETStandard.Library": "1.6.1",
  "System.ComponentModel.Primitives": "4.2.0",
  "System.Xml.XmlSerializer": "4.2.0",
  "UniversalSerialPort": "1.0.0-*",
  "System.Security.Cryptography.Algorithms": "4.0.0",
  "System.Threading.Thread": "4.3.0"
 },

"frameworks": {
  "netcoreapp1.1":
{
    "imports": "dnxcore50",
    "dependencies":
  {
      "Microsoft.NETCore.App":
    {
        "type": "platform",
        "version": "1.1.0"
      }
    }
 },
"netstandard1.4":
{
      "imports": "dnxcore50"
},

 "net462": {
   "dependencies": {
   }
 }
}
}

编译时我收到了多个这样的警告：

C:\Program Files (x86)\MSBuild\Microsoft.NetNative\ARM\ilc\IlcInternals.targets(936,5): warning : ILTransform_0003: Method 'GroupSelect.StartGroupLoop(byte[])' will always throw an exception due to the missing method 'ThreadStart..ctor(object, IntPtr)'. There may have been a missing assembly.

所有警告都是关于引用库的。

我试过这个主题的解决方案，但没有任何帮助： Can't find System.Threading 4.0.10 on Raspberry Pi on Windows 10 IoT

Answer 1

我解决了问题。

首先 - 在 UWP 项目引用的每个项目中，最好有 UWP 配置（示例）：

"uap10.0": {
      "imports": "dnxcore50",
                "runtimes": {
        "win10-arm": {},
        "win10-arm-aot": {},
        "win10-x86": {},
        "win10-x86-aot": {},
        "win10-x64": {},
        "win10-x64-aot": {}
      },
      "dependencies": {"System.Threading.Thread": "4.0.10.0" }
}

第二件事 - 您不能在 UWP 应用程序中使用线程。您必须将线程重写为 async、await 并改用 Task。
