Question

我正在尝试使用Visual Studio 2015 CTP中的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，并将该文件夹复制到我的AWS EC2实例。我在IIS中设置了应用程序，因此它指向我发布的应用程序中的wwwroot目录。

在尝试运行应用程序时，我不断获得黄色死亡屏幕（YSOD）。查看事件查看器，我可以看到抛出未处理的异常：

Exception message: Could not load file or assembly 'file:///C:\inetpub\wwwroot\appname\approot\packages\kre-clr-win-x64.1.0.0-beta3\bin\kre.clr.managed.dll' or one of its dependencies

果然，该文件在磁盘上不存在。它从未与我的应用程序一起发布。但是，我有x86版本：kre-clr-win-x86.1.0.0-beta3。该目录随我的应用程序一起发布。

因此，出于某种原因，我的应用程序正在使用kre-clr-win-x86发布，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。我该如何解决这个问题？

修改

以下是已发布的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web.cmd文件（虽然我不确定该文件的特定用例是什么），如果我运行该应用程序，则会在localhost：5000上提供服务。如果我在本地访问该页面，它可以工作。那么它可能与IIS管道有关吗？

这是完整的堆栈跟踪：

Answer 1

如果要在64位操作系统上部署应用程序，则需要使用64位KLR。

这是您将应用程序与KLR捆绑在一起的方式：

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

这将生成一个包含您的应用程序，其依赖项和CLR的文件夹。只需复制到网络服务器，你应该好好去。
