无法运行本机 iOS 使用 .net 6.0 构建的应用程序：libhostpolicy.dylib 缺失

Question

我正在尝试使用 .net 6.0.100 (RC1) 构建 & 运行本机 iOS 应用程序。我不使用 MAUI。我同时使用 Visual Studio 2022 for Mac 和 Jetbrains' Rider。该应用程序是默认应用程序。 .csproj 文件如下所示：

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net6.0-ios14.0</TargetFramework>
    <SupportedOSPlatformVersion>14.0</SupportedOSPlatformVersion>
    <RuntimeIdentifier>iossimulator-x64</RuntimeIdentifier>
    <AssemblyName>Application.iOS</AssemblyName>
    <RootNamespace>Application.iOS</RootNamespace>
    <LangVersion>default</LangVersion>
    <Nullable>enable</Nullable>
    <OutputType>Exe</OutputType>
  </PropertyGroup>
</Project>

我可以成功构建应用程序，但我不能运行它:

Cannot use file stream for [/Users/xxx/Application/src/Application.iOS/bin/iPhoneSimulator/Debug/net6.0-ios14.0/iossimulator-x64/Application.iOS.deps.json]: No such file or directory
A fatal error was encountered. The library 'libhostpolicy.dylib' required to execute the application was not found in '/Users/xxx/Application/src/Application.iOS/bin/iPhoneSimulator/Debug/net6.0-ios14.0/iossimulator-x64/'.
Failed to run as a self-contained app.
  - The application was run as a self-contained app because '/Users/xxx/Application/src/Application.iOS/bin/iPhoneSimulator/Debug/net6.0-ios14.0/iossimulator-x64/Application.iOS.runtimeconfig.json' did not specify a framework.
  - If this should be a framework-dependent app, specify the appropriate framework in '/Users/xxx/Application/src/Application.iOS/bin/iPhoneSimulator/Debug/net6.0-ios14.0/iossimulator-x64/Application.iOS.runtimeconfig.json'.

文件内容如下Application.iOS.runtimeconfig.json:

{
  "runtimeOptions": {
    "tfm": "net6.0",
    "includedFrameworks": [
      {
        "name": "Microsoft.NETCore.App",
        "version": "6.0.0-rc.1.21451.13"
      },
      {
        "name": "Microsoft.iOS",
        "version": "**FromWorkload**"
      }
    ],
    "configProperties": {
      "System.ComponentModel.TypeConverter.EnableUnsafeBinaryFormatterInDesigntimeLicenseContextSerialization": false,
      "System.Diagnostics.Debugger.IsSupported": true,
      "System.Diagnostics.Tracing.EventSource.IsSupported": false,
      "System.Globalization.Invariant": false,
      "System.Net.Http.EnableActivityPropagation": false,
      "System.Net.Http.UseNativeHttpHandler": true,
      "System.Resources.ResourceManager.AllowCustomResourceTypes": false,
      "System.Resources.UseSystemResourceKeys": false,
      "System.Runtime.Serialization.EnableUnsafeBinaryFormatterSerialization": false,
      "System.StartupHookProvider.IsSupported": false,
      "System.Threading.Thread.EnableAutoreleasePool": true,
      "System.Text.Encoding.EnableUnsafeUTF7Encoding": false
    }
  }
}

我知道 libhostpolicy.dylib 文件存在于 dotnet 的安装文件夹中。我复制了文件，却得到了这个错误：

/usr/local/share/dotnet/dotnet /Users/***/Application/src/Application.iOS/bin/iPhoneSimulator/Debug/net6.0-ios14.0/iossimulator-x64/Application.iOS.dll
Cannot use file stream for [/Users/***Application/src/Application.iOS/bin/iPhoneSimulator/Debug/net6.0-ios14.0/iossimulator-x64/Application.iOS.deps.json]: No such file or directory

如何在 .net 6 上运行构建/运行本机 iOS 应用程序？

Answer 1

Rider 尚未准备好运行 iOS .net6 上的应用程序。也就是说，应用程序可以通过运行ning 以下命令启动：

dotnet build -t:run
