出于某种原因，我无法使用 DNX 和 Kestrel 运行一个简单的、开箱即用的 ASP.NET 5 / Core 1.0 Web 应用程序。运行后dnx web我不断收到错误：

Error: Unable to load application or execute command 'Microsoft.AspNet.Server.Kestrel'. Available commands: web, ef.

我的项目.json：

}

是的，我以前跑过dnu restore。我安装了这些运行时：

dnx-clr-win-x64.1.0.0-rc1-update1
dnx-clr-win-x64.1.0.0-rc1-update2
dnx-clr-win-x86.1.0.0-rc1-update1
dnx-clr-win-x86.1.0.0-rc1-update2
dnx-coreclr-win-x64.1.0.0-rc1-update2

我真的希望有人知道这个问题可能来自哪里。

看来我在解决依赖项和程序集绑定方面遇到了问题。每当我运行dnu build它时，它构建得很好，我可以看到所有 nuget 包依赖项都在 C:\users\*****\.dnx\packages 中解析/恢复。

但是，在运行时dnx web，我不断收到我提到的错误。我启用了 FusionLog，似乎早期的 nuget 包依赖关系现在没有解决。我不断收到这样的错误：

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.AspNet.Hosting, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' or one of its dependencies. The system cannot find the file specified.

所以我现在知道问题出在哪里了。如果我暂时将所需的 dll 复制到/C:/Users/*****/.dnx/runtimes/dnx-clr-win-x86.1.0.0-rc1-update2/bin它似乎可以解决，但这不是解决方案。

更新 2

似乎问题出在 clr 运行时。每当我通过输入 cmd 使用 coreclr 时dnvm use 1.0.0-rc1-update1 -a x86 -r coreclr，dnx web应用程序运行得很好。

我尝试重新安装 clr，为 x64 和 x86 安装 update1 和 update2，但错误仍然存​​在。只有 coreclr 似乎工作。有什么想法吗？
