我正在寻找一个通过PowerShell后台作业弹出WPF表单的选项。
我尝试了不同的方法，但失败了。所以，寻求你的帮助。
我可以弹出正常的windows窗体，但当我决定使用WPF时，挑战就来了。代码在没有后台作业的情况下工作得很好。
这是我完整的PowerShell代码，将在后台运行。您的帮助将不胜感激。提前感谢。
下面的代码保存在一个文件“BackgroundJob.ps1”中。这个文件被下面提到的Show-Popups函数调用。

[cmdletbinding()]
Param($TaskName,$ScriptPath)

[void][System.Reflection.Assembly]::LoadWithPartialName('presentationframework')

                $Error  | Out-File -FilePath "$env:temp\RuntimeError.log"  -Force -Append 
            }

下面是创建后台作业的代码

Start-Job -ScriptBlock {   
    Import-Module "C:\Data\MyFunctions.ps1" -Force
    Show-Popups -ScriptPath 'C:\Data'
  
}

Show-Popups -是调用Powershell后台作业脚本“BackgroundJob.ps1”的函数。
