Question

我不明白为什么这个项目没有开始。它的日志无法正常解释。我使用asp core，项目版本为1.0.1。我安装了.NET Core 1.1 Runtime＆Hosting Bundle服务器，因为这是最新版本。我无法更新项目。

您的日志中充满了异常 System.BadImageFormatException 。当我尝试在IIS上运行ASP.NET Core应用程序时遇到了相同的问题。显然，Web应用程序和Web服务器之间存在处理器类型不匹配。我通过在Visual Studio的“发布”设置中将“目标运行时”设置为“可移植”来解决此问题。您使用其他Web服务器，但是此异常始终具有相同的原因。您需要使所有dll文件都具有相同的位数，因为Web服务器会在进程内运行应用程序。
