c# - 无法在 .NET Core 中加载文件或程序集 'System.Runtime, Version=4.1.0.0'

Question

Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime, Version=4.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

我在我的应用程序中使用 AssemblyLoadContext，所以我有 "System.Runtime.Loader": "4.0.0"作为依赖项，但在发布我的项目后我有上述错误。

dotnet --version
1.0.0-preview2-003121

{
  "version": "1.0.0-*",
  "buildOptions": {
    "emitEntryPoint": true
  },

  "dependencies": {
    "Microsoft.NETCore.App": {
      "type": "platform",
      "version": "1.0.0"
    },
    "CommandLineArgumentsParser": "3.0.4",
    "System.Runtime.Loader": "4.0.0",
    "Microsoft.Extensions.DependencyModel": "1.0.0",
    "System.Runtime": "4.1.0"
  },

  "frameworks": {
    "netcoreapp1.0": {
      "imports": "dnxcore50"
    }
  }
}

使用 visual studio 我可以运行我的应用程序但是使用 dotnet 命令行我有上述错误。有人可以帮助我吗？

Answer 1

您“将项目创建为 .NET 4.6.2”并尝试使用 dotnet core 进行编译。您需要在第一个或第二个之间做出选择。发生错误是因为项目文件 vcxproj 引用了 .net 4.6.2，而 dotnet 将无法使其正常工作。

今天，您可能想要清理您的 vcxproj 文件以及您的 dotnet 配置，将您的源代码迁移到一个新项目(我推荐 dotnet core 2)，这应该会运行。
