这是已知 错误.

可以通过使用您自己的代码替换SecurityStampValidator.OnValidateIdentity来解决此问题-重新生成Cookie时，它会忘记在新Cookie中添加"RememberMe"属性，这会使新Cookie不再持久.

It can be fixed by replacing SecurityStampValidator.OnValidateIdentity with your own code - when the cookie is re-generated, it forgets to add "RememberMe" property in the new cookie and this makes the new cookie not persistent.

我认为此问题已在v2.2中解决，但此版本尚未投入生产.遗憾的是，现在我找不到原始的错误报告.

I think this has been resolved in v2.2, but this version is not out for production yet. And sadly I can't find the original bug-report for this now.
