在同一个问题苦苦挣扎了几天后,我们遇到了这个解决方案:
http://connect.microsoft.com/VisualStudio/feedback/details/806542/fix-internet-explorer-11-not-detected-correctly-by-net-4-0-framework-when-custom-browser-files-被使用。
将新的 .browser 文件添加到 App_Browsers 文件夹;我们将文件命名为“IE11.browser”,如果 App_Browsers 文件夹不存在,则创建它。
然后我们简单地将正文从上面的链接复制到新创建的文件中,重新部署,现在不再有 _doPostBack 错误。
文件的正文如下所示:
<browsers>
<browser id="IE11" parentID="Mozilla">
<identification>
<userAgent match="Trident\/7.0; rv:(?'version'(?'major'\d+)(\.(?'minor'\d+)?)(?'letters'\w*))(?'extra'[^)]*)" />
<userAgent nonMatch="IEMobile" />
</identification>
<capture>
<userAgent match="Trident/(?'layoutVersion'\d+)" />
</capture>
<capabilities>
<capability name="browser" value="IE" />
<capability name="layoutEngine" value="Trident" />
<capability name="layoutEngineVersion" value="${layoutVersion}" />
<capability name="extra" value="${extra}" />
<capability name="isColor" value="true" />
<capability name="letters" value="${letters}" />
<capability name="majorversion" value="${major}" />
<capability name="minorversion" value="${minor}" />
<capability name="screenBitDepth" value="8" />
<capability name="type" value="IE${major}" />
<capability name="version" value="${version}" />
</capabilities>
</browser>
<!-- Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11,0) like Gecko -->
<browser id="IE110" parentID="IE11">

<capability name="jscriptversion" value="5.6" />
<capability name="javascript" value="true" />

<capability name="tagwriter" value="System.Web.UI.HtmlTextWriter" />
<capability name="vbscript" value="true" />
</capabilities>
</browser>
</browsers>
我们不必将 .Net 版本从 4 升级到 4.5,现在一切正常。
希望这可以帮助遇到同样令人沮丧的问题的人!
