This introduces another design pattern that is used to evaluate current and desired state in a DSC resource. This command is meant to be used in a DSC resource from both _Test_ and _Set_. The evaluation is made in _Set_ to make sure to only change the properties that are not in the desired state. Properties that are in the desired state should not be changed again. This design pattern also handles when the command `Invoke-DscResource` is called with the method `Set`, which with this design pattern will evaluate the properties correctly. >[!NOTE] >This design pattern is not widely used in the DSC resource modules in the >DSC Community, the only known use is in SqlServerDsc. This design pattern >can be viewed as deprecated, and should be replaced with the design pattern >that uses the command [`Compare-DscParameterState`](Compare-DscParameterState). See the other design patterns that uses the command [`Compare-DscParameterState`](Compare-DscParameterState) or [`Test-DscParameterState`](Test-DscParameterState). .PARAMETER CurrentValues The current values that should be compared to to desired values. Normally the values returned from Get-TargetResource. .PARAMETER DesiredValues The values set in the configuration and is provided in the call to the functions *-TargetResource, and that will be compared against current values. Normally set to $PSBoundParameters. .PARAMETER Properties An array of property names, from the keys provided in DesiredValues, that will be compared. If this parameter is left out, all the keys in the DesiredValues will be compared. .PARAMETER IgnoreProperties An array of property names, from the keys provided in DesiredValues, that will be ignored in the comparison. If this parameter is left out, all the keys in the DesiredValues will be compared. .PARAMETER CimInstanceKeyProperties A hashtable containing a key for each property that contain a collection of CimInstances and the value is an array of strings of the CimInstance key properties. @{ Permission = @('State') } .OUTPUTS System.Collections.Hashtable[] .NOTES Returns an array containing a hashtable with metadata for each property that was evaluated.

It is designed to enable scripts to display user messages in the UI language selected by the current user. Optionally the `Get-LocalizedData` saves the hash table in the variable that is specified by the value of the `BindingVariable` parameter. Get-LocalizedData imports data from .psd1 files in language-specific subdirectories of the script directory and saves them in a local variable that is specified in the command. The command selects the subdirectory and file based on the value of the $PSUICulture automatic variable. When you use the local variable in the script to display a user message, the message appears in the user's UI language. You can use the parameters of G-LocalizedData to specify an alternate UI culture, path, and file name, to add supported commands, and to suppress the error message that appears if the .psd1 files are not found. The G-LocalizedData command supports the script internationalization initiative that was introduced in Windows PowerShell 2.0. This initiative aims to better serve users worldwide by making it easy for scripts to display user messages in the UI language of the current user. For more information about this and about the format of the .psd1 files, see about_Script_Internationalization. ```mermaid graph LR Argument{Parameter set?} -->|"Only UICulture (DefaultUICulture = en-US)"| UseUIC Argument -->|"Only DefaultUICulture"| GetUIC[[Get OS Culture]] GetUIC --> LCID127{"Is LCID = 127?<br>(in variant culture)"} Argument -->|"Both UICulture and DefaultUICulture"| UseUIC UseUIC[Use UICulture] --> LCID127 LCID127 -->|"No"| SetUIC[[Set UICulture]] LCID127 -->|"Yes"| UseDC[Use default culture] UseDC --> SetUIC SetUIC --> SearchFile[[Find UICulture<br>localization file]] SearchFile --> FileExist FileExist{localization<br>file exist?} -->|"No"| ParentCulture{Parent culture<br>exist?} ParentCulture -->|"Yes"| UseParentC[Use parent culture] UseParentC --> SetUIC ParentCulture -->|"No"| EvalDefaultC{Evaluate<br>default>br>culture?} EvalDefaultC -->|"Yes"| UseDC EvalDefaultC -->|"No"| EvalStillLCID127{Still invariant?} FileExist -->|"Yes"| EvalStillLCID127 EvalStillLCID127 -->|"Yes, Use Get-LocalizedDataForInvariantCulture"| GetFile[[Get localization strings]] EvalStillLCID127 -->|"No, Use Import-LocalizedData"| GetFile ``` .PARAMETER BindingVariable Specifies the variable into which the text strings are imported. Enter a variable name without a dollar sign ($). In Windows PowerShell 2.0, this parameter is required. In Windows PowerShell 3.0, this parameter is optional. If you omit this parameter, Import-LocalizedData returns a hash table of the text strings. The hash table is passed down the pipeline or displayed at the command line. When using Import-LocalizedData to replace default text strings specified in the DATA section of a script, assign the DATA section to a variable and enter the name of the DATA section variable in the value of the BindingVariable parameter. Then, when Import-LocalizedData saves the imported content in the BindingVariable, the imported data will replace the default text strings. If you are not specifying default text strings, you can select any variable name. If the BindingVariable parameter is not specified, Import-LocalizedData returns a hashtable of the text strings. The hash table is passed down the pipeline or displayed at the command line. .PARAMETER UICulture Specifies an alternate UI culture. The default is the value of the $PsUICulture automatic variable. Enter a UI culture in <language>-<region> format, such as en-US, de-DE, or ar-SA. The value of the UICulture parameter determines the language-specific subdirectory (within the base directory) from which Import-LocalizedData gets the .psd1 file for the script. The command searches for a subdirectory with the same name as the value of the UICulture parameter or the $PsUICulture automatic variable, such as de-DE or ar-SA. If it cannot find the directory, or the directory does not contain a .psd1 file for the script, it searches for a subdirectory with the name of the language code, such as de or ar. If it cannot find the subdirectory or .psd1 file, the command fails and the data is displayed in the default language specified in the script. .PARAMETER BaseDirectory Specifies the base directory where the .psd1 files are located. The default is the directory where the script is located. Import-LocalizedData searches for the .psd1 file for the script in a language-specific subdirectory of the base directory. .PARAMETER FileName Specifies the name of the data file (.psd1) to be imported. Enter a file name. You can specify a file name that does not include its .psd1 file name extension, or you can specify the file name including the .psd1 file name extension. The FileName parameter is required when Import-LocalizedData is not used in a script. Otherwise, the parameter is optional and the default value is the base name of the script. You can use this parameter to direct Import-LocalizedData to search for a different .psd1 file. For example, if the FileName is omitted and the script name is FindFiles.ps1, Import-LocalizedData searches for the FindFiles.psd1 data file. .PARAMETER SupportedCommand Specifies cmdlets and functions that generate only data. Use this parameter to include cmdlets and functions that you have written or tested. For more information, see about_Script_Internationalization. .PARAMETER DefaultUICulture Specifies which UICulture to default to if current UI culture or its parents culture don't have matching data file. For example, if you have a data file in 'en-US' but not in 'en' or 'en-GB' and your current culture is 'en-GB', you can default back to 'en-US'. .NOTES Before using Import-LocalizedData, localize your user messages. Format the messages for each locale (UI culture) in a hash table of key/value pairs, and save the hash table in a file with the same name as the script and a .psd1 file name extension. Create a directory under the script directory for each supported UI culture, and then save the .psd1 file for each UI culture in the directory with the UI culture name. For example, localize your user messages for the de-DE locale and format them in a hash table. Save the hash table in a <ScriptName>.psd1 file. Then create a de-DE subdirectory under the script directory, and save the de-DE <ScriptName>.psd1 file in the de-DE subdirectory. Repeat this method for each locale that you support. Import-LocalizedData performs a structured search for the localized user messages for a script. Import-LocalizedData begins the search in the directory where the script file is located (or the value of the BaseDirectory parameter). It then searches within the base directory for a subdirectory with the same name as the value of the $PsUICulture variable (or the value of the UICulture parameter), such as de-DE or ar-SA. Then, it searches in that subdirectory for a .psd1 file with the same name as the script (or the value of the FileName parameter). If Import-LocalizedData cannot find a subdirectory with the name of the UI culture, or the subdirectory does not contain a .psd1 file for the script, it searches for a .psd1 file for the script in a subdirectory with the name of the language code, such as de or ar. If it cannot find the subdirectory or .psd1 file, the command fails, the data is displayed in the default language in the script, and an error message is displayed explaining that the data could not be imported. To suppress the message and fail gracefully, use the ErrorAction common parameter with a value of SilentlyContinue. If Import-LocalizedData finds the subdirectory and the .psd1 file, it imports the hash table of user messages into the value of the BindingVariable parameter in the command. Then, when you display a message from the hash table in the variable, the localized message is displayed. For more information, see about_Script_Internationalization. This command should preferably be used at the top of each resource PowerShell module script file (.psm1). It will automatically look for a file in the folder for the current UI culture, or default to the UI culture folder 'en-US'. The localized strings file can be named either `<ScriptFileName>.psd1`, e.g. `DSC_MyResource.psd1`, or suffixed with `strings`, e.g. `DSC_MyResource.strings.psd1`. Read more about localization in the section [Localization](https://dsccommunity.org/styleguidelines/localization/) in the DSC Community style guideline. .OUTPUTS System.Collections.Hashtable .EXAMPLE $script:localizedData = Get-LocalizedData Imports the localized strings for the current OS UI culture.

This directly gets the data from the DefaultUICulture, but without calling "Import-LocalizedData" which throws when the pwsh session is configured to be of invariant culture (as in the Guest Config agent). .DESCRIPTION The Get-LocalizedDataForInvariantCulture grabs the data from a localized string data psd1 file, without calling Import-LocalizedData which errors when called in a powershell session with the Globalization-Invariant mode enabled (https://docs.microsoft.com/en-us/dotnet/core/compatibility/globalization/6.0/culture-creation-invariant-mode). Instead, this function reads and executes the content of a psd1 file in a constrained language mode that only allows basic ConvertFrom-stringData. .PARAMETER BaseDirectory Specifies the base directory where the .psd1 files are located. The default is the directory where the script is located. Import-LocalizedData searches for the .psd1 file for the script in a language-specific subdirectory of the base directory. .PARAMETER FileName Specifies the base name of the data file (.psd1) to be imported. Enter a file name. You can specify a file name that does not include its .psd1 file name extension, or you can specify the file name including the .psd1 file name extension. The FileName parameter is required when Get-LocalizedDataForInvariantCulture is not used in a script. Otherwise, the parameter is optional and the default value is the base name of the calling script. You can use this parameter to directly search for a specific .psd1 file. For example, if the FileName is omitted and the script name is FindFiles.ps1, Get-LocalizedDataForInvariantCulture searches for the FindFiles.psd1 or FindFiles.strings.psd1 data file. .PARAMETER SupportedCommand Specifies cmdlets and functions that generate only data. Use this parameter to include cmdlets and functions that you have written or tested. For more information, see about_Script_Internationalization. .PARAMETER DefaultUICulture Specifies which UICulture to default to if current UI culture or its parents culture don't have matching data file. For example, if you have a data file in 'en-US' but not in 'en' or 'en-GB' and your current culture is 'en-GB', you can default back to 'en-US'. .NOTES The Get-LocalizedDataForInvariantCulture should only be used when we want to avoid using Import-LocalizedData, such as when doing so will fail because the powershell session is in Globalization-Invariant mode: https://docs.microsoft.com/en-us/dotnet/core/compatibility/globalization/6.0/culture-creation-invariant-mode Before using Get-LocalizedDataForInvariantCulture, localize your user messages to the desired default locale (UI culture, usually en-US) in a hash table of key/value pairs, and save the hash table in a file with the same name as the script or module with a .psd1 file name extension. Create a directory under the module base or script's parent directory for each supported UI culture, and then save the .psd1 file for each UI culture in the directory with the UI culture name. For example, localize your user messages for the de-DE locale and format them in a hash table. Save the hash table in a <ScriptName>.psd1 file. Then create a de-DE subdirectory under the script directory, and save the de-DE <ScriptName>.psd1 file in the de-DE subdirectory. Repeat this method for each locale that you support. Import-LocalizedData performs a structured search for the localized user messages for a script. Get-LocalizedDataForInvariantCulture only search in the BaseDirectory specified. It then searches within the base directory for a subdirectory with the same name as the value of the $DefaultUICulture variable (specified or default to en-US), such as de-DE or ar-SA. Then, it searches in that subdirectory for a .psd1 file with the same name as provided FileName such as FileName.psd1 or FileName.strings.psd1. .EXAMPLE Get-LocalizedDataForInvariantCulture -BaseDirectory .\source\ -FileName DscResource.Common -DefaultUICulture en-US This is an example, usually it is only used by Get-LocalizedData in DSC resources to import the localized strings when the Culture is Invariant (id 127). #> function Get-LocalizedDataForInvariantCulture { [CmdletBinding()] param ( [Parameter(Mandatory = $true)] [System.String] $BaseDirectory, [Parameter(Mandatory = $true, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true)] [System.String] $FileName, [Parameter()] [System.String] [ValidateNotNull()] $DefaultUICulture = 'en-US' ) begin { if ($FileName -match '\.psm1$|\.ps1$|\.psd1$') { Write-Debug -Message 'Found an extension to the file name to search.
