出于某种原因，我无法使用DNX和Kestrel运行简单的，开箱即用的ASP.NET 5 / Core 1.0 Web应用程序。运行dnx web后，我不断收到错误：
Error: Unable to load application or execute command 'Microsoft.AspNet.Server.Kestrel'. Available commands: web, ef.

是的，我之前已经开过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。
更新
我似乎遇到了解决依赖关系和程序集绑定的问题。每当我运行dnu build它构建得很好，我可以看到所有nuget包依赖关系在C：\ users \ ***** \ .dnx \ packages中解析/恢复。
然而，在运行dnx web时，我不断收到我提到的错误。我启用了FusionLog，似乎现在还没有解决早期的nuget包依赖项。我一直遇到这样的错误：
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所在。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
似乎问题是clr运行时。每当我通过输入cmd dnvm use 1.0.0-rc1-update1 -a x86 -r coreclr后跟dnx web来使用coreclr时，该应用程序运行正常。
我尝试重新安装clr，同时为x64和x86安装update1和update2，但错误仍然存在。只有coreclr似乎有效。任何人的想法？
