推荐答案

问题是与IE 11发的userAgent字符串，其中点网4.0框架或下方不承认与Internet Explorer。
你可以通过你的服务器升级到斑点网4.5或任何解决这个问题
您可以添加在Web应用程序的文件夹内App_Browsers文件具有以下条目添加一个ie.Browser文件

The problem is with the userAgent string sent by IE 11 where Dot Net 4.0 frameworks or below do not recognize as Internet Explorer. You can fix this problem either by upgrading your server to Dot Net 4.5 or you can add add an ie.Browser file in your web application within the folder App_Browsers with the following entry

<browser id="InternetExplorer" parentID="Mozilla">
    <identification>
        <userAgent match="Trident/(?'layoutVersion'[7-9]|0*[1-9]\d+)(\.\d+)?;(.*;)?\s*rv:(?'version'(?'major'\d+)(\.(?'minor'\d+)))" />
        <userAgent nonMatch="IEMobile" />
        <userAgent nonMatch="MSIE " />
    </identification>

    <capabilities>
        <capability name="browser"              value="InternetExplorer" />
        <capability name="version"              value="${version}" />
        <capability name="majorversion"         value="${major}" />
        <capability name="minorversion"         value="${minor}" />
        <capability name="layoutEngine"         value="Trident" />
        <capability name="layoutEngineVersion"  value="${layoutVersion}" />
        <capability name="type"                 value="InternetExplorer${major}" />
    </capabilities>
</browser>
