Question

使用新的171010-1400 Windows版本和Visual Studio Update 4，我以前工作的配置变得混乱。正如我从windbg输出中看到的那样，iisexpress.exe在第一次或第二次请求时失败，我想这与设置cookie有关。我从调试中看到的全部内容如下：

ModLoad: 00007ff9`417a0000 00007ff9`417cb000   C:\WINDOWS\system32\dwmapi.dll
18312 w3wphost!W3WP_HOST::IncrementMessages [w3wphost.cxx @ 4073]:IncrementMessages called

IISUTIL2!IsLocalRequest+0x2e:

我在哪里可以获得有关此IsLocalRequest调用的更多信息？我想IISExpress.exe不是开源的。

Update1：我认为IISUTIL dll不在符号服务器上：

Answer 1

就我而言，问题的根源是StackoverflowException。我的输出窗口中没有消息表明此问题。

Answer 2

根据微软（https://github.com/Microsoft/dotnet/issues/523）的说法： 1）这是httpd.sys中的已知回归，很快将在开发人员构建中修复 2）IIS Express pdbs将不会发布，这是他们“有意识的决定”

Answer 3

出于历史目的。这是我发生的，因为有一个代码错误。

在我的情况下，尝试使用 AutoMapper.Mapper.Map（model），但未设置映射定义。同样，此调用是在隐式运算符中进行的：

public static implicit operator DestinyType (ModelType model)
{
      return Mapper.Map <DestinyType> (model);
}

我的替代选择是使用类似的东西：

     public static implicit operator DestinyType (ModelType model)
     {
         var mapper = Mapper.Configuration.FindTypeMapFor <ModelType, DestinyType> ();

         if (mapper == null)
         {
             throw new InvalidOperationException ();
         }

         return Mapper.Map <DestinyType> (model);
     }

Answer 4

我也遇到这个问题，IIS Express因此错误而关闭。经过一段时间的摸摸，我发现它来自我的一个类中IDisposable的错误实现。

Answer 5

我遇到此错误消息是因为我将视图命名为“视图”，将其更改为“详细信息”解决了该问题。

iisexpress.exe在IsLocalRequest调用中因访问冲突而崩溃
