Jobs are a feature of ShowUI that make it easy to run things in the background ShowUI jobs are mostly like the jobs in regular PowerShell Let's launch a few jobs and explore how

$jobs = @()             
$jobs += New-Label "look at all of the colors..." -AsJob            
foreach ($n in 1..5) {            
    $jobs += New-Rectangle -width 100 -height 100 -Fill {            
        [Windows.Media.Colors] |             
            Get-Member -Static -MemberType Properties |             
            Select-Object -ExpandProperty Name |

You can also interact with the window. To demostrate this, let's go ahead and launch a simple details dialog

$job = New-StackPanel -ControlName 'Get-PersonalInformation' -Columns 1 -Children {            
    New-Label "What is your first name?"            
    New-TextBox -Name Firstname            
    New-Label "What is your last name?"            
    New-TextBox -Name Lastname            
    New-Label "When were you born?"            
    Select-Date -Name Birthdate                    
} -asjob

It's possible to get the UI value out of the form while it's running

    Update-WPFJob -Command {             
        Get-UIValue -Ui $window.Content             
    }
