使用System.DirectoryServices.AccountManagement获取FileNotFoundException

Question

我有以下代码来获取当前登录用户的完整显示名称：

using System.DirectoryServices.AccountManagement;

public class Form1
{
    private void Button1_Click(object sender, EventArgs e)
    {
        var up = UserPrincipal.Current;
        var dn = up.DisplayName;
    }
}

问题是它在var up = UserPrincipal.Current;行失败并出现FileNotFoundException。地球上到底发生了什么？我在未连接到域的计算机上使用Windows 10。我使用.NET FW 4.5.1。

这是一个堆栈跟踪
