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

如果我删除该行
<%= Html.AntiForgeryToken() %>
一切都有效,任何想法可能导致这个?如果这是一个MVC或.NET问题,我希望找到一个解决方案更幸运,所以我猜这与我的配置有关。
我已经尝试重新安装MVC框架,看看是不是因为我在SP1之前安装但我仍然遇到同样的问题。 Google和SO搜索没有得出任何确切的结论。

清除浏览器缓存和Cookie,一切正常。

如果站点已经部署并且您正在进行维护(包括ASP.NET MVC程序集更新),则不能选择清除浏览器缓存。这是我使用的解决方案:
@Html.AntiForgeryTokenReset() @* use this instead*@
这是扩展方法
public static MvcHtmlString AntiForgeryTokenReset(this HtmlHelper htmlHelper)
{
try
{
return htmlHelper.AntiForgeryToken();
} catch (Exception ex)
{
var request = HttpContext.Current.Request;
request.Cookies.Clear();
return htmlHelper.AntiForgeryToken();
}
}

现在看来这个问题已经解决了。看看http://forums.asp.net/p/1388671/2960554.aspx
