在 ASP.NET Core 应用程序 (RC2) 中使用 net451 库

Question

我正在尝试将我的 ASP.NET 5 RC1 项目升级到 ASP.NET Core RC2 项目。我遇到了一些问题，因为我使用的库还不支持 .NET Core，所以我必须在完整的框架上运行。这在 RC1 中运行良好，但我无法找到在 RC2 中实现此目标的正确方法。

我有一个可以恢复包并正确构建的类库。我有一个引用类库的测试项目。当我尝试构建测试项目时，出现以下错误：

> dotnet build
Project TenantService (.NETFramework,Version=v4.5.1) was previously compiled. Skipping compilation.
Project TenantServiceTests (.NETCoreApp,Version=v1.0) will be compiled because expected outputs are missing

C:\projects\TenantService\test\TenantServiceTests\project.json(9,31): error NU1001: The dependency Microsoft.CSharp could not be resolved.

这两个项目的 project.json 文件如下所示：

src\TenantService\project.json

{
  "version": "1.0.0-*",

  "dependencies": {
    "NETStandard.Library": "1.5.0-rc2-24027",
    "Microsoft.Extensions.Options": "1.0.0-rc2-final",
    "Newtonsoft.Json": "8.0.4-beta1",
    "MongoDB.Driver": "2.2.4",
    "StackExchange.Redis": "1.1.603"
  },

  "frameworks": {
    "net451": {}
  }
}

test\TenantServiceTests\project.json

{
  "version": "1.0.0-*",
  "testrunner": "xunit",
  "description": "TenantServiceTests Class Library",
  "authors": [ "Henning" ],

  "dependencies": {
    "xunit": "2.1.0",
    "TenantService": "1.0.0-*",
    "dotnet-test-xunit": "1.0.0-rc2-build10015"
  },

  "frameworks": {
    "netcoreapp1.0": {
      "dependencies": {
        "Microsoft.NETCore.App": {
          "type": "platform",
          "version": "1.0.0-rc2-3002702"
        }
      },
      "imports": [
        "net451"
      ]
    }
  }
}

我应该如何正确设置才能在我的应用中使用 net451 库？

Answer 1

依赖 mscorlib 无法解析

我昨天遇到了同样的问题。问题是测试项目的project.json 的目标是netcoreapp1.0。相反，您可以将 net451 框架作为您正在测试的服务，它应该“正常工作”。

{
  "version": "1.0.0-*",
  "testrunner": "xunit",
  "description": "TenantServiceTests Class Library",
  "authors": [ "Henning" ],

  "dependencies": {
    "xunit": "2.1.0",
    "TenantService": "1.0.0-*",
    "dotnet-test-xunit": "1.0.0-rc2-build10015"
  },

  "frameworks": {
    "net451": { }
  }
}
