你能分享一下你的 project.json 文件吗？ - Shawn Wildermuth

{ "webroot": "wwwroot", "version": "1.0.0-*", "dependencies": { "Microsoft.AspNet.IISPlatformHandler": "1.0.0-beta8", "Microsoft.AspNet.Server.Kestrel": "1.0.0-beta8" }, "commands": { "web": "Microsoft.AspNet.Server.Kestrel" }, "frameworks": { "dnx451": { "dependencies": { "Microsoft.AspNet.StaticFiles": "1.0.0-beta8" } }, "dnxcore50": { } }, "exclude": [ "wwwroot", "node_modules" ], "publishExclude": [ ".user", ".vspscc" ] } - user5555457

@ShawnWildermuth 我已经在我的原始问题中更新了我的 project.json。 - user5555457

Answer 1

从您的错误信息可以看出，UseStaticFiles 可用于 DNX 4.5.1 框架，但不适用于 DNX Core 5.0。

您应该将依赖项添加到 Microsoft.AspNet.StaticFiles，不仅在 dnx451 上，还要在 dnxcore50 上，在您的 project.json 文件中。您可以将依赖项从 "frameworks" 键中移除，并将其放置到 "dependencies" 键中，以使其对两个框架都可用。

{
  ...

  "dependencies": {
    "Microsoft.AspNet.IISPlatformHandler": "1.0.0-beta8",
    "Microsoft.AspNet.Server.Kestrel": "1.0.0-beta8",
    "Microsoft.AspNet.StaticFiles": "1.0.0-beta8",
  },

  ...

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

  ...
}

对于 Asp.Net Core MVC，您需要安装 Nuget 包 Microsoft.AspNetCore.StaticFiles。 - Dhanuka777
