Question

我们有一个混合的MVC和asp.net应用程序，客户错误设置为关闭。

 <customErrors mode="Off" >

当抛出未处理的异常时，Global.asax会像这样处理错误。

       Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)

        Dim exception = Server.GetLastError()
        Dim httpContext = CType(sender, HttpApplication).Context

        ExecuteErrorController(httpContext, exception)
    End Sub

    Sub ExecuteErrorController(httpContext As HttpContext, exception As Exception)

        Dim routeData = New RouteData
        routeData.Values("controller") = "Error"
        routeData.Values("errorType") = 10 '
        Response.Clear()
        Dim httpException As HttpException = TryCast(exception, HttpException)
        If httpException Is Nothing Then
            routeData.Values.Add("action", "Index")
        Else
            'It's an Http Exception, Let's handle it.
            Select Case httpException.GetHttpCode()
                Case HttpStatusCode.Forbidden
                    ' forbidden - i.e. failed Data.HasAccess checks
                    routeData.Values.Add("action", "HttpError403")
                    Exit Select
                Case 404
                    ' Page not found.
                    routeData.Values.Add("action", "HttpError404")
                    Exit Select
                Case 500
                    ' Server error.
                    routeData.Values.Add("action", "Index")
                    Exit Select
                Case Else

                    ' Here you can handle Views to other error codes.
                    ' I choose a General error template  
                    routeData.Values.Add("action", "Index")
                    Exit Select
            End Select
        End If

        ' Pass exception details to the target error View.
        routeData.Values.Add("exception", exception)

        Dim controller As IController = New ErrorController()
        httpContext.ClearError()
        Dim requestContext As RequestContext = New RequestContext(New HttpContextWrapper(httpContext), routeData)

        Response.TrySkipIisCustomErrors = True
        Server.ClearError()


            controller.Execute(requestContext)
End Sub

这一切都适用于开发环境和当前的实时环境（带有iis 7.5的Server 2008 R2），但在部署到我们的新环境（Windows Server 2012 R2和IIS 8）时，我们得到一个500错误页面，这似乎只会发生对于500个错误，404错误似乎处理得很好。

我知道Application_Error，ExecuteErrorController和控制器被调用，因为错误是通过控制器记录的，但控制器返回的视图没有显示而是我得到了

此页面目前无法处理此请求。 HTTP 错误500

我是否遗漏了移动到iis 8的内容以使其正常工作？

MVC iis8“自定义错误关闭”错误处理
