    # CHANGELOG
    
    ## Version 1.7.0
    
    - New helper: Uninstall-VisualStudioVsixExtension.
    - New helper: Get-VisualStudioInstallerHealth (checks for corruption observed sometimes after installer update)
    - Install-VisualStudioInstaller will check for installer corruption after update and will attempt to repair the installer by renaming the installer directory and retrying the update.
    - The VS Installer will also be repaired before each VS install/update/modify/uninstall operation.
    - Before each VS update/modify operation, the required VS Installer version is determined from the channel manifest and the VS Installer is updated (to the newest currently available version, using the VS Bootstrapper) if it does not meet the version requirement. This works around reliability problems in the VS Installer update mechanism if it is triggered during a VS update/modify operation.
    - Package parameter '--noUpdateInstaller' can be specified to turn off the VS Installer repair/update logic listed above. To prevent this parameter from being passed to the native installer, specify also '--no-noUpdateInstaller'.
    - Package parameter '--installLayoutPath D:\Path' can be specified to indicate the offline installation source for VS workload/component addition (VS product installation/update still needs --bootstrapperPath).
    - Package parameter '--noWeb' can be specified for fully offline installation (no Internet access). Works only together with --bootstrapperPath (for product packages) or --installLayoutPath (for workload packages).
    - Install-VisualStudio will now update existing VS products. To turn this off, specify '--no-update' in package parameters.
    
    ## Version 1.6.0
    
    - New helper: Install-VisualStudioVsixExtension. Supports Visual Studio 2010-2017 and replaces Install-ChocolateyVsixPackage.
    - New helper: Get-VisualStudioVsixInstaller.
    - Parameters: --add, --remove, --addProductLang and --removeProductLang can now be specified multiple times in package parameters ([GH-16](https://github.com/jberezanski/ChocolateyPackages/issues/16)).
    - Parameters: --add, --remove specified in package parameters are no longer ignored when adding/removing workloads and components ([GH-27](https://github.com/jberezanski/ChocolateyPackages/issues/27)).
    - New parameter for Add-VisualStudioWorkload and Add-VisualStudioComponent: -RequiredProductVersion. If a workload/component package provides a value for this parameter and a Visual Studio product supported by that package but not meeting this requirement is found, package installation will fail with a message asking the user to upgrade that product.
    - ISO mounting feature ported from existing VS 2015 packages. The ISO path can be specified in package parameters as '--IsoPath D:\path\vs.iso' or via an environment variable named 'visualStudio:isoImage'.
     Supported by Install-VisualStudio.
    - For compatibility with existing VS 2015 packages, Install-VisualStudio also recognizes an environment variable named 'visualStudio:setupFolder' and will attempt to use the installer executable from there, unless the bootstrapperPath package parameter is present. The installer executable name is obtained from the Url parameter (vs_`<ProductName>`.exe) or, if the Url is not provided or does not contain the executable name, vs_Setup.exe is assumed.
    - New package parameter: '--RegenerateAdminFile'. When installing Visual Studio 2015, this parameter instructs the packages to create a fresh admin file by invoking the VS installer with the /CreateAdminFile option, instead of using the default admin file embedded in the package. This can be used to ensure that feature names passed via the --Features package parameter are up to date and will be recognized by the VS installer (some feature names tend to change with minor VS installer updates), because the package will raise an error if one of the features specified by the user is not present in the admin file. Ignored for VS 2017.
    - Log files generated during VS 2015 installation now have unique names (with timestamps), preventing overwrite during repeated package installation attempts.
    - XML comments in VS 2015 admin files should not cause errors anymore.
    
    ## Version 1.5.1
    
    - Changed the method of locating the VS 2017 installer during modify and uninstall operations to not depend on Uninstall registry
      keys anymore. This avoids the problem caused by registry key changes in a recent VS 2017 update.
    
    ## Version 1.5.0
    
    - New helpers: Add-VisualStudioComponent, Remove-VisualStudioComponent
    - New package parameter: '--layout D:\Path' can be used to create an offline installation source ("layout").
      Package installation using this parameter will throw an error at the end (code 814) so that Chocolatey does not register the package as installed.
      Supported by the Install-VisualStudio helper, both for Visual Studio 2017 and 2015.
    - New package parameter: '--bootstrapperPath D:\Path\vs_Enterprise.exe' can be used to install Visual Studio from a previously created offline installation source ("layout").
      Supported by the Install-VisualStudio helper, both for Visual Studio 2017 and 2015.
    - New helper: Get-VisualStudioInstaller.
      Retrieves an object containing the executable path and version number of the Visual Studio Installer (VS 2017+) installed on the system, if present.
    - New helper: Install-VisualStudioInstaller.
      Installs or updates the Visual Studio Installer (VS 2017+).
      Can work from an offline installation source using package parameters, syntax: '--bootstrapperPath D:\Path\vs_Enterprise.exe --offline D:\Path\vs_installer.opc'
    
    ## Version 1.4.1
    
    - Fixed encoding of recently added files.
    
    ## Version 1.4.0
    
    - Install-VisualStudio can detect existing Visual Studio 2017 products and skip the installation (an interim solution before upgrading is implemented).
    - Remove-VisualStudioProduct warns the user not to allow the Chocolatey Auto Uninstaller to run.
    
    ## Version 1.3.0
    
    - New helper: Get-VisualStudioInstance.
    
    ## Version 1.2.0
    
    - Added switch -IncludeRecommendedComponentsByDefault to Add-VisualStudioWorkload. The user may disable it by passing '--no-includeRecommended' in package parameters.
    
    ## Version 1.1.0
    
    - Added helper: Remove-VisualStudioProduct.
    - Fixed argument string generation in Start-VisualStudioModifyOperation (affects Add-VisualStudioWorkload and Remove-VisualStudioWorkload).
    
    ## Version 1.0.0
    
    - Initial release with helpers: Install-VisualStudio, Uninstall-VisualStudio, Add-VisualStudioWorkload, Remove-VisualStudioWorkload.
    - Tested with Visual Studio 2017 and 2015, should also work with earlier Visual Studio versions.

    function Install-VisualStudioVsixExtension
    {
    <#
    .SYNOPSIS
    Installs or updates a Visual Studio VSIX extension.
    
    .DESCRIPTION
    This function installs a Visual Studio VSIX extension by invoking
    the Visual Studio extension installer (VSIXInstaller.exe).
    The latest installer version found on the machine is used.
    The extension is installed in all Visual Studio instances present on the
    machine the extension is compatible with.
    
    .PARAMETER PackageName
    The name of the package - while this is an arbitrary value, it's
    recommended that it matches the package id.
    Alias: Name
    
    .PARAMETER VsixUrl
    The URL of the package to be installed.
    Prefer HTTPS when available. Can be HTTP, FTP, or File URIs.
    Alias: Url
    
    .PARAMETER Checksum
    The checksum hash value of the Url resource. This allows a checksum to
    be validated for files that are not local. The checksum type is covered
    by ChecksumType.
    
    .PARAMETER ChecksumType
    The type of checkum that the file is validated with - valid
    values are 'md5', 'sha1', 'sha256' or 'sha512' - defaults to 'md5'.
    MD5 is not recommended as certain organizations need to use FIPS
    compliant algorithms for hashing - see
    https://support.microsoft.com/en-us/kb/811833 for more details.
    The recommendation is to use at least SHA256.
    
    .PARAMETER VsVersion
    NOT USED. The newest available VSIXInstaller.exe program
    will be used and the extension will be installed in all supported
    Visual Studio products present on the machine.
    Alias: VisualStudioVersion
    
    .PARAMETER Options
    Additional options passed to Get-ChocolateyWebFile when downloading
    remote resources, such as custom HTTP headers.
    
    .PARAMETER File
    Same as VsixUrl, will be used if VsixUrl is empty. Provided for
    compatibility reasons.

    # chocolatey-visualstudio.extension
    
    This is a Chocolatey extension that simplifies building Chocolatey packages which install and configure Microsoft Visual Studio.
    
    ## Functions
    
    ### Install-VisualStudio
    
    Installs a product from the Visual Studio family (Professional, Enterprise, Community, Build Tools etc.).

    ### Uninstall-VisualStudio
    
    For Visual Studio editions using the classic MSI installer (Visual Studio up to 2017 Preview 3), uninstalls an installed product
    from the Visual Studio family (Professional, Enterprise, Community, Build Tools etc.).
    For Visual Studio editions using the new "Willow" installer of Visual Studio 2017 RC, uninstalls the Visual Studio Installer
    and all installed products from the Visual Studio 2017 family.
    
    ### Add-VisualStudioWorkload
    
    Adds a workload (a set of features) to installed products from the Visual Studio 2017 family.
    Supports the new "Willow" installer of Visual Studio 2017 RC only.
    
    ### Remove-VisualStudioWorkload
    
    Removes a workload (a set of features) from installed products from the Visual Studio 2017 family.
    Supports the new "Willow" installer of Visual Studio 2017 RC only.
    
    ### Add-VisualStudioComponent
    
    Adds a component (an individual feature) to installed products from the Visual Studio 2017 family.
    Supports the new "Willow" installer of Visual Studio 2017 RC only.
    
    ### Remove-VisualStudioComponent

    ### Get-VisualStudioInstance
    
    Returns information about all Visual Studio instances installed on the machine.
    The returned objects contain properties: InstallationPath, InstallationVersion, ProductId, ChannelId.
    The last two properties have values only for instances of Visual Studio 2017.
    
    ### Get-VisualStudioInstaller
    
    Returns information about the Visual Studio Installer, if installed on the machine.
    The returned object contain properties: Path, Version.
    Supports the new "Willow" installer of Visual Studio 2017 RC only.
    
    ### Install-VisualStudioInstaller

    ### Get-VisualStudioVsixInstaller
    
    Locates all versions of the Visual Studio extension installer installed on the machine.
    The returned object contain properties: Path, Version.
    Supports Visual Studio 2017 and earlier Visual Studio versions.
    
    ### Install-VisualStudioVsixExtension
    
    Installs or updates a Visual Studio extension (*.vsix).
    Replaces Install-ChocolateyVsixPackage, adding support for Visual Studio 2017.
    
    ## Installation
    
    End users typically do not install this package directly - it is usually installed automatically as a dependency of another package.
    
    Package authors interested in testing the usage of individual functions may install this package via Chocolatey: `choco install chocolatey-visualstudio.extension`.
    
    ## Usage
    
    To  be able to use functions from this extension in a Chocolatey package, add the following to the `nuspec` specification:
    
        <dependencies>
            <dependency id="chocolatey-visualstudio.extension" version="SPECIFY_LATEST_VERSION" />
        </dependencies>
    
    **NOTE**: Make sure you use adequate _minimum_ version.
    
    ## Testing

    Keep in mind that functions may work fully only in the context of the `chocolateyInstaller` module.
    
    To get the list of functions, load the module directly and invoke the following command:
    
        Get-Command -Module chocolatey-visualstudio
    
    To get help for a specific function use the [help](https://msdn.microsoft.com/en-us/powershell/reference/5.1/microsoft.powershell.core/get-help) command:
    
        help Install-VisualStudio -Full
    
    ### Acknowledgement
    
    The structure of the Markdown files was inspired by [chocolatey-core.extension](https://github.com/chocolatey/chocolatey-coreteampackages/tree/master/extensions/chocolatey-core.extension).
    
    The module code was initially based on the logic of the `visualstudio2015community` package, later extensively expanded and improved in the `visualstudio2017enterprise` package.
