# Initialize - Bootstraps the nuget type system $bootstrapper = & (Resolve-Path "$PSScriptRoot\packaging.ps1") $loaded = @{ "NuGet.Frameworks" = "netstandard2.0" } <# .Synopsis A simplistic cmdlet for getting the target framework of the current PowerShell session. .Description This cmdlet is used to get the target framework of the current PowerShell session. It is used by Import-Package to determine which dlls to load from a NuGet package into the session. .Example Get-Dotnet # Example Return: Net,Version=v4.7.2 #> function Get-Dotnet { [CmdletBinding()] param() Process { $bootstrapper.system } } <# .Synopsis Imports NuGet/Nupkg packages downloaded by PackageManagement .Description PackageManagement's default package providers (NuGet and PowerShellGet/Gallery) lack the ability to load their NuGet Packs into PowerShell. While PowerShellGallery Packages can be loaded with `Import-Module`, they import the packs using a module manifest, not the actual nuspec. This module provides a `Import-Package` cmdlet for importing packages by the nuspec instead of the module manifest. By offering the commands `Import-Package` and `Import-Module` separately, this module allows you to handle the C# dependencies (.nuspec) and PowerShell dependencies (.psd1) from the same pack file on their own. This is useful for dependency control. A couple of use cases for this feature: - You want to rewrite an existing powershell module using the same C# dependencies, but you want to provide a different PowerShell API. - You are using multiple PowerShell modules that depend on the same C# dependencies, and don't want to load the same C# dependencies multiple times. - You want to inject your own C# dependencies into a PowerShell module. .Parameter Name The name of the package to import. Alias: PackageName ParameterSetName: Managed (default) .Parameter Provider The name of the PackageManagement Provider to use. Defaults to 'NuGet' as PowerShellGallery modules can already be imported with Import-Module. Alias: ProviderName, PackageProvider ParameterSetName: Managed (default) .Parameter Version The version of the package to import. Defaults to the latest version. ParameterSetName: Managed (default) .Parameter Package The SoftwareIdentity object of the package to import (returned by Get-Package) ParameterSetName: Managed-Object .Parameter Path The path to the .nupkg file to import. Alias: PackagePath ParameterSetName: Unmanaged .Parameter TargetFramework The target framework of the package to import. Defaults to TFM of the current PowerShell session. .Parameter SkipLib Skip loading the crossplatform dlls from the package. .Parameter SkipRuntimes Skip loading the platform specific dlls from the package. .Parameter PostInstallScript A scriptblock to run after the package is imported. Defaults to a scriptblock that does nothing. .Parameter Loadmanifest A hashtable of package names mapped to manifest objects. The manifest object can contain the following properties: - Skip: A boolean or hashtable with the following properties: - Lib: A boolean indicating whether to skip loading the crossplatform dlls from the package. - Runtimes: A boolean indicating whether to skip loading the platform specific dlls from the package. - Script: A scriptblock to run after the package is imported. - Framework: The target framework of the package to import. - NativeDir: The directory to load native dlls from. - This is the recommended way to place native dlls for a specific package. .Parameter NativeDir The directory to place and load native dlls from. Defaults to the current directory. Recommended to be used in conjunction with Loadmanifest. .Example # These are the actual packages that make up the foundation of this module.
