我刚刚更新到 .NET 3.5 SP1,我曾经工作的 ASP.NET MVC 页面现在已经停止工作。
尝试加载页面时,我得到以下 YSOD
[CryptographicException: Padding is invalid and cannot be removed.]

如果我删除线
<%= Html.AntiForgeryToken() %>
一切都恢复正常了,有什么想法可能导致这种情况吗?如果这是 MVC 或 .NET 问题,我本来希望找到解决方案的运气更好,所以我猜这与我的配置有关。
我尝试重新安装 MVC 框架,看看是否是因为我在 SP1 之前安装,但我仍然遇到同样的问题。Google 和 SO 搜索尚未得出任何确定的结论。
