当尝试在 asp.net 应用程序中打开特定页面时，我得到一个 YSOD：
Server Error in '/CommonLoon' Application.
Parser Error

首先，为什么注释掉的行有问题？
其次...无论如何，第二个：该文件中没有（或不再）有该评论；相反，现在是该行：
<!-- 5/6/2013: Replace 1.8.16 with a newer css, such as http://code.jquery.com/ui/1.10.2/themes/smoothness/jquery-ui.css? The "custom" part of the name of the file makes me hesitate to make a change, though... -->
该文件的旧版本来自哪里？解决方案中的任何地方都没有出现“可能想要”这个短语......？？？
更新
还是陌生的；我只是取消了一些之前注释掉 jQjuery 以测试旧功能的注释，并没有注意到有一条注释应该阻止代码编译，即：
$("#BeginDate").datepicker( try this as a anytime date component
...但它编译并运行！Murgatroid 的天堂！那是怎么回事？！？！？
