winforms – 使用Windows窗体锁定脚本终止后的PowerShell ISE分

我在这里有一个有趣的问题.我创建一个日历选择器,供我们创建帐户时使用.它工作正常,并且仍在进行中,但是我注意到,当我在PowerShell ISE中运行脚本时,几分钟后它会锁定(我可以在之前几分钟编辑和保存代码).事件日志中没有任何内容.我得到一个对话框,说PowerShell是无响应的.内存使用情况似乎也正常.我不知道发生了什么.

无论我如何运行Powershell ISE(以管理员身份运行,运行另一个帐户和正常的ISE),我都在运行Windows 8.1.

一个同事建议它可能是公寓模型,所以我尝试过STA和MTA,但是问题出现在两种情况之中.当从控制台主机运行相同的代码时,不会发生这种情况.
