PRE-REQUIREMENTS
最好的步骤是捕获正在发生的事情.
The best step is catch what exactly is going on.
-
下载并使用它" Sysinternals进程监视器(PM)".
运行PM并创建过滤器'进程名称''是''iisexpress.exe'".现在，您仅显示来自IIS的捕获事件.
Run PM and create filter "'Process Name' 'is' 'iisexpress.exe'". Now you show capture events only from IIS.
使用键 F5 运行构建VS项目，并查看PM结果.
Run building your VS project with key F5 and watch PM results.
双击第一行，打开"Operation = Process Start"，然后查看运行IIS的完整参数的详细信息，尤其是命令行".
Open with double click first row with "Operation = Process Start" and look detail for full parameters to run IIS especially "Command line".
打开"命令行界面(CLI)，称为"命令外壳与 Win + R 写入"cmd"，将IIS命令行值放入并使用 Enter 运行.现在您看到了确切的错误:
Open "Command Line Interface (CLI)" called "Command shell" with Win+R write "cmd" put IIS command line value and run with Enter. Now you see the exact error:
"C:\Program Files\IIS Express\iisexpress.exe" /config:"C:\Users\{user_name}\Documents\IISExpress\config\applicationhost.config" /site:"{project_name}" /apppool:"Clr4IntegratedAppPool"
解决方案
案例"apppool"
以下开关需要一个值:'apppool'
The following switch requires a value: 'apppool'
-
打开文件
Open file
%userprofile%\documents\iisexpress\config\applicationhost.config`
在站点>站点"部分中找到您的命名项目，或者通过bindingInformation通过VS附件找到.在版本中，将您用于项目的版本的另一个参数"applicationPool"添加到应用程序"部分.
Find in section "sites > site" your named project or by bindingInformation by attached from VS. Add to section "application" another parameter "applicationPool" from version what you use for your project.
<application path="/" applicationPool="Clr4IntegratedAppPool">
现在进行测试，完全关闭VS，再次打开项目并进行构建.
Now test it, close fully VS, open project again and build.
案例"config"
- 删除WebMatrix"或创建符号链接"，或在该位置上将其替换.
