确定IIS/ASP.NET是否识别IE 11浏览器版本

因此，当微软推出新的浏览器版本时，他们需要对.NET Framework进行更新，使其能够识别浏览器版本，否则某些功能可能会被破坏

我看到了这一点——某些页面只在兼容性视图中工作，它们也在Chrome中工作。然后，其他页面将无法在兼容性视图中工作，但在浏览器强制执行时，它们将在边缘模式下工作。我们有可怕的标签

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /> 

在网站上以兼容模式运行时，它是：

Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; InfoPath.3; .NET4.0C; .NET4.0E; MS-RTC EA 2)

现在，解决方案中的ASP_浏览器文件夹不包含任何浏览器定义文件

我在C:\Windows\Microsoft.NET\Framework文件夹下有以下.browser文件：

在Web.Config中启用跟踪后，我得到了以下值得注意的信息：
