从 AppHistoryViewModel 中删除 setter 属性后，它起作用了.

After removing setter property from AppHistoryViewModel it worked.

我从代码中删除了以下几行，在 sonarQube 报告中看不到漏洞

I removed below set of lines from the code and I can see no longer Vulnerability in sonarQube report

 set
        {
            if (HttpContext.Current != null)
            {
                HttpContext.Current.Session[SessionKeys.AppHistory] = value;
            }
        }
