这是工作脚本。我发现webview2.dll需要在脚本目录中。我从安装webview2的地方手动删除了它们。最终将在nuGet包安装后在脚本中包含. dll的文件副本：

function New-XamlGui {
    [CmdletBinding()]
    param (
        [parameter(Mandatory,ParameterSetName="String")]
        [string]
        $XamlXmlString,
        [Parameter(Mandatory,ParameterSetName="File")]
        [ValidateScript({Test-Path $_})]
        [string]
        $XamlFile
    )
    
    begin {
        if (-not ( ([System.Management.Automation.PSTypeName]'windows.markup.xamlreader').type ) ) {
            try {
                [void][System.Reflection.Assembly]::LoadWithPartialName('presentationframework')
            }
            catch {
                #This looks odd but will stop execution of the rest of the script.
                $PSCmdlet.ThrowTerminatingError($_)
            }
        }
    }
    
    process {

        if ($PSCmdlet.ParameterSetName -eq "File"){
            $XamlXmlString = Get-Content -Raw $XamlFile
            if ( -not $XamlXmlString){
                $PSCmdlet.ThrowTerminatingError(
                    ( new-object System.Management.Automation.ErrorRecord -ArgumentList @(
                        [System.Management.Automation.RuntimeException]'EmptyOrMissingFile',
                        'EasyGUI.UnableToReadFileOrEmpty',
                        [System.Management.Automation.ErrorCategory]::InvalidData,
                        $XamlFile
                        )
                    )
                )
            }
        }

        # fix up xaml from VS:
        $XamlXmlString = $XamlXmlString -replace '(x:)?Class=".*?"',''
        $XamlXmlString = $XamlXmlString -replace "x:Name=","Name="
        $XamlXmlString = $XamlXmlString -replace '(mc:)?Ignorable=".*?"',''

        try {
            $InputXAML = [xml]$XamlXmlString
        } catch {
            #This looks odd but will stop execution of the rest of the script.
            $PSCmdlet.ThrowTerminatingError($_)
        }
        $XMLReader = New-Object System.Xml.XmlNodeReader $InputXAML
        try {
            $XAMLForm = [Windows.Markup.XamlReader]::Load($XMLReader)

                )
            )
        }
        

        $NamedControls = @{}
        foreach ($node in ($InputXAML.SelectNodes("//*[@Name]") ) ) {
            $NamedControls[$node.name] = $XAMLForm.FindName($node.name)
        }
