NOTE: This applies to both open source and commercial editions of Chocolatey.

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://chocolatey.org/api/v2. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Enter your internal repository url

(this should look similar to https://chocolatey.org/api/v2)

4. Choose your deployment method:


choco upgrade chocolatey-visualstudio.extension -y --source="'STEP 3 URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:


choco upgrade chocolatey-visualstudio.extension -y --source="'STEP 3 URL'" 
$exitCode = $LASTEXITCODE

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0
}

Exit $exitCode

.SYNOPSIS
Installs Visual Studio

.DESCRIPTION
Installs Visual Studio with ability to specify additional features and supply product key.

.PARAMETER PackageName
The name of the VisualStudio package - this is arbitrary.
It's recommended you call it the same as your nuget package id.

.PARAMETER Url
This is the url to download the VS web installer.

.PARAMETER ChecksumSha1
The SHA-1 hash of the VS web installer file.

.EXAMPLE
Install-VisualStudio -PackageName VisualStudio2015Community -Url 'http://download.microsoft.com/download/zzz/vs_community.exe' -ChecksumSha1 'ABCDEF0123456789ABCDEF0123456789ABCDEF12'

.OUTPUTS
None

.NOTES
This helper reduces the number of lines one would have to write to download and install Visual Studio.
This method has no error handling built into it.

## 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

To test the functions you can import the module directly or via the `chocolateyInstaller.psm1` module:

    PS> Import-Module $Env:ChocolateyInstall\helpers\chocolateyInstaller.psm1
    PS> Import-Module $Env:ChocolateyInstall\extensions\chocolatey-visualstudio\*.psm1

You can now test any of the functions:

    PS> Install-VisualStudio `
        -PackageName 'visualstudio2017enterprise' `
        -ApplicationName 'Microsoft Visual Studio Enterprise 2017 RC' `
        -Url 'https://download.microsoft.com/download/4/2/9/429C6D6F-543E-4BB4-A2C7-4EFA7F8DE59D/vs_Enterprise.exe' `
        -Checksum '493364F350657B537077E72E7400DBF8875CD773' `
        -ChecksumType 'SHA1' `
        -InstallerTechnology 'WillowVS2017OrLater' `
        -ProgramsAndFeaturesDisplayName 'Microsoft Visual Studio 2017'

    PS> Add-VisualStudioWorkload `
        -PackageName 'visualstudio2017-workload-manageddesktop' `
        -Workload 'Microsoft.VisualStudio.Workload.ManagedDesktop' `
        -VisualStudioYear '2017' `
        -ApplicableProducts @('Community', 'Professional', 'Enterprise')

    PS> Remove-VisualStudioWorkload `
        -PackageName 'visualstudio2017-workload-manageddesktop' `
        -Workload 'Microsoft.VisualStudio.Workload.ManagedDesktop' `
        -VisualStudioYear '2017' `
        -ApplicableProducts @('Community', 'Professional', 'Enterprise')

    PS> Uninstall-VisualStudio `
        -PackageName 'visualstudio2017enterprise' `
        -ApplicationName 'Microsoft Visual Studio Enterprise 2017 RC' `
        -UninstallerName 'vs_installer.exe' `
        -InstallerTechnology 'WillowVS2017OrLater' `
        -ProgramsAndFeaturesDisplayName 'Microsoft Visual Studio 2017'

    # this must be run from a script and requires the presence of an AdminDeployment.xml file next to the script
    Install-VisualStudio `
        -PackageName 'visualstudio2017enterprise' `
        -ApplicationName 'Microsoft Visual Studio Enterprise 15 Preview 3' `
        -Url 'https://download.microsoft.com/download/e/e/6/ee6e936e-6323-4b51-a6f3-7b276b7e168a/vs_enterprise.exe' `
        -Checksum '6A63984CAFE972D655817395CC12054068077015' `
        -ChecksumType 'SHA1' `
        -InstallerTechnology 'MsiVS2015OrEarlier'

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.

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
