Screenshot of Solution explorer with errors

就在最近，我一直在尝试新的asp.net功能并遇到了这个错误。我尝试使用app.UseStaticFiles并添加了依赖项，但由于某种原因它似乎没有编译？

错误是：

Project.json包含：

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

  "dependencies": {

    "Microsoft.AspNet.IISPlatformHandler": "1.0.0-rc1-final",
    "Microsoft.AspNet.Server.Kestrel": "1.0.0-rc1-final",
    "Microsoft.AspNet.StaticFiles": "1.0.0-rc1-final"
  },

  "commands": {

    "web": "Microsoft.AspNet.Server.Kestrel"
  },

  "frameworks": {

    "dnx451": { },
    "dnxcore50": { }
  },

  "exclude": [

    "wwwroot",
    "node_modules"
  ],
  "publishExclude": [

    "**.user",
    "**.vspscc"
  ]
}

输出：

Answer 1

在dnu恢复期间

could not be resolved通常意味着，它无法在您配置的nuget上找到NuGet包。

在Visual Studio中，转到Tools/Nuget Package Manager/Package Manager Settings并检查其中配置的内容。

至少应该有一个指向nuget.org的条目：https://www.nuget.org/api/v2

如果有，那么您可能在解决方案级别上有一个nuget.config。检查解决方案文件夹或nuget.config文件夹中是否有\.Nuget文件。

不能使用＆＃34; Microsoft.AspNet.StaticFiles＆＃34;：＆＃34; 1.0.0-rc1-final＆＃34;
