asp.net - 无法加载文件或程序集 kre-clr-win - 如何指定 KRE？

Question

我正在尝试在 Visual Studio 2015 CTP 中使用 ASP.NET 5 构建我的第一个应用程序。我刚刚将应用程序发布到文件系统，并将文件夹复制到我的 AWS EC2 实例。我在 IIS 中设置了该应用程序，因此它指向我发布的应用程序中的 wwwroot 目录。

尝试运行该应用程序时，我不断收到蓝屏死机 (YSOD)。查看事件查看器，我可以看到抛出了未处理的异常:

异常消息:无法加载文件或程序集“file:///C:\inetpub\wwwroot\appname\approot\packages\kre-clr-win-x64.1.0.0-beta3\bin\” kre.clr.managed.dll' 或其依赖项之一

果然，磁盘上不存在该文件。它从未与我的申请一起发布。不过，我有 x86 版本:kre-clr-win-x86.1.0.0-beta3。该目录是与我的应用程序一起发布的。

由于某种原因，我的应用程序是使用 kre-clr-win-x86 发布的，但是当我尝试运行已发布的应用程序时，它正在寻找 kre-clr-win-x64。如何解决这个问题？

这是在发布的 wwwroot 文件夹中生成的 web.config:

<configuration>
  <appSettings>
    <add key="kpm-package-path" value="..\approot\packages" />
    <add key="bootstrapper-version" value="1.0.0-beta3" />
    <add key="runtime-path" value="..\approot\packages" />
    <add key="kre-version" value="1.0.0-beta3" />
    <add key="kre-clr" value="clr" />
    <add key="kre-app-base" value="..\approot\src\appname" />
  </appSettings>
</configuration>

作为发布的一部分，生成了一个 web.cmd 文件(尽管我不确定该文件的特定用例是什么)，如果我运行它，该应用程序将在 localhost:5000 上提供服务。如果我在本地访问该页面，它就可以工作。那么这可能与 IIS 管道有关？

这是完整的堆栈跟踪:

如果您在 64 位操作系统上部署应用程序，则需要使用 64 位 KLR。

这是将应用程序与 KLR 捆绑在一起的方式:

kpm bundle --runtime kre-clr-win-x64.1.0.0-beta3

这将生成一个文件夹，其中包含您的应用程序、其依赖项和 CLR。只需复制到网络服务器就可以了。
