DESCRIPTION
The dotnet-install scripts perform a non-admin installation of the .NET SDK, which
includes the .NET CLI and the shared runtime. There are two scripts:
• A PowerShell script that works on Windows.
• A bash script that works on Linux/macOS.
[!NOTE] .NET collects telemetry data. To learn more and how to opt out, see .NET SDK
telemetry.
Purpose
The intended use of the scripts is for Continuous Integration (CI) scenarios, where:
• The SDK needs to be installed without user interaction and without admin rights.
• The SDK installation doesn’t need to persist across multiple CI runs.
The typical sequence of events:
• CI is triggered.
• CI installs the SDK using one of these scripts.
• CI finishes its work and clears temporary data including the SDK installation.
To set up a development environment or to run apps, use the installers rather than these
scripts.
Recommended version
We recommend that you use the stable version of the scripts:
• Bash (Linux/macOS): <https://dot.net/v1/dotnet-install.sh>
• PowerShell (Windows): <https://dot.net/v1/dotnet-install.ps1>
Script behavior
Both scripts have the same behavior. They download the ZIP/tarball file from the CLI
build drops and proceed to install it in either the default location or in a location
specified by -InstallDir|--install-dir.
By default, the installation scripts download the SDK and install it. If you wish to only
obtain the shared runtime, specify the -Runtime|--runtime argument.
By default, the script adds the install location to the $PATH for the current session.
Override this default behavior by specifying the -NoPath|--no-path argument. The script
doesn’t set the DOTNET_ROOT environment variable.
Before running the script, install the required dependencies.
You can install a specific version using the -Version|--version argument. The version
must be specified as a three-part version number, such as 2.1.0. If the version isn’t
specified, the script installs the latest version.
The install scripts do not update the registry on Windows. They just download the zipped
binaries and copy them to a folder. If you want registry key values to be updated, use
the .NET installers.
OPTIONS
• -Architecture|--architecture <ARCHITECTURE>
Architecture of the .NET binaries to install. Possible values are <auto>, amd64, x64,
x86, arm64, and arm. The default value is <auto>, which represents the currently
running OS architecture.
• -AzureFeed|--azure-feed
Specifies the URL for the Azure feed to the installer. We recommended that you don’t
change this value. The default value is https://dotnetcli.azureedge.net/dotnet.
• -Channel|--channel <CHANNEL>
Specifies the source channel for the installation. The possible values are:
• Current - Most current release.
• LTS - Long-Term Support channel (most current supported release).
• Two-part version in A.B format, representing a specific release (for example, 2.1 or
3.0).
• Three-part version in A.B.Cxx format, representing a specific SDK release (for
example, 5.0.1xx or 5.0.2xx). Available since the 5.0 release.
The version parameter overrides the channel parameter when any version other than latest
is used.
The default value is LTS. For more information on .NET support channels, see the .NET
Support Policy (https://dotnet.microsoft.com/platform/support/policy/dotnet-core) page.
• -DryRun|--dry-run
If set, the script won’t perform the installation. Instead, it displays what command
line to use to consistently install the currently requested version of the .NET CLI.
For example, if you specify version latest, it displays a link with the specific version
so that this command can be used deterministically in a build script. It also displays
the binary’s location if you prefer to install or download it yourself.
• -FeedCredential|--feed-credential
Used as a query string to append to the Azure feed. It allows changing the URL to use
non-public blob storage accounts.
• --help
Prints out help for the script. Applies only to bash script. For PowerShell, use Get-
Help ./dotnet-install.ps1.
• -InstallDir|--install-dir <DIRECTORY>
Specifies the installation path. The directory is created if it doesn’t exist. The
default value is %LocalAppData%on Windows and /usr/share/dotnet* on Linux/macOS.
Binaries are placed directly in this directory.
• -JSonFile|--jsonfile <JSONFILE>
Specifies a path to a global.json file that will be used to determine the SDK version.
The global.json file must have a value for sdk:version.
• -NoCdn|--no-cdn
Disables downloading from the Azure Content Delivery Network (CDN) and uses the uncached
feed directly.
• -NoPath|--no-path
If set, the installation folder isn’t exported to the path for the current session. By
default, the script modifies the PATH, which makes the .NET CLI available immediately
after install.
• -ProxyAddress
If set, the installer uses the proxy when making web requests. (Only valid for
Windows.)
• -ProxyBypassList <LIST_OF_URLS>
If set with ProxyAddress, provides a list of comma-separated urls that will bypass the
proxy. (Only valid for Windows.)
• ProxyUseDefaultCredentials
If set, the installer uses the credentials of the current user when using proxy address.
(Only valid for Windows.)
• -Quality|--quality <QUALITY>
Downloads the latest build of the specified quality in the channel. The possible values
are: daily, signed, validated, preview, GA. Works only in combination with channel.
Not applicable for current and LTS channels and will be ignored if one of those channels
is used.
For an SDK installation, use channel in A.B or A.B.Cxx format. For a runtime
installation, use channel in A.B format.
The version parameter overrides the channel and quality parameters when any version
other than latest is used.
Available since since the 5.0 release.
• -Runtime|--runtime <RUNTIME>
Installs just the shared runtime, not the entire SDK. The possible values are:
• dotnet - the Microsoft.NETCore.App shared runtime.
• aspnetcore - the Microsoft.AspNetCore.App shared runtime.
• windowsdesktop - the Microsoft.WindowsDesktop.App shared runtime.
• --runtime-id <RID> [Deprecated]
Specifies the runtime identifier for which the tools are being installed. Use linux-x64
for portable Linux. (Only valid for Linux/macOS and for versions earlier than .NET Core
2.1.)
--os <OPERATING_SYSTEM>
Specifies the operating system for which the tools are being installed. Possible values
are: osx, linux, linux-musl, freebsd, rhel.6. (Valid for .NET Core 2.1 and later.)
The parameter is optional and should only be used when it’s required to override the
operating system that is detected by the script.
• -SharedRuntime|--shared-runtime
[!NOTE] This parameter is obsolete and may be removed in a future version of the
script. The recommended alternative is the -Runtime|--runtime option.
Installs just the shared runtime bits, not the entire SDK. This option is equivalent to
specifying -Runtime|--runtime dotnet.
• -SkipNonVersionedFiles|--skip-non-versioned-files
Skips installing non-versioned files, such as dotnet.exe, if they already exist.
• -UncachedFeed|--uncached-feed
Allows changing the URL for the uncached feed used by this installer. We recommended
that you don’t change this value.
• -Verbose|--verbose
Displays diagnostics information.
• -Version|--version <VERSION>
Represents a specific build version. The possible values are:
• latest - Latest build on the channel (used with the -Channel option).
• Three-part version in X.Y.Z format representing a specific build version; supersedes
the -Channel option. For example: 2.0.0-preview2-006120.
If not specified, -Version defaults to latest.
EXAMPLES
• Install the latest long-term supported (LTS) version to the default location:
Windows:
./dotnet-install.ps1 -Channel LTS
macOS/Linux:
./dotnet-install.sh --channel LTS
• Install the latest preview version of the 6.0.1xx SDK to the specified location:
Windows:
./dotnet-install.ps1 -Channel 6.0.1xx -Quality preview -InstallDir C:\cli
macOS/Linux:
./dotnet-install.sh --channel 6.0.1xx --quality preview --install-dir ~/cli
• Install the 3.0.0 version of the shared runtime:
Windows:
./dotnet-install.ps1 -Runtime dotnet -Version 3.0.0
macOS/Linux:
./dotnet-install.sh --runtime dotnet --version 3.0.0
• Obtain script and install the 2.1.2 version behind a corporate proxy (Windows only):
Invoke-WebRequest 'https://dot.net/v1/dotnet-install.ps1' -Proxy $env:HTTP_PROXY -ProxyUseDefaultCredentials -OutFile 'dotnet-install.ps1';
./dotnet-install.ps1 -InstallDir '~/.dotnet' -Version '2.1.2' -ProxyAddress $env:HTTP_PROXY -ProxyUseDefaultCredentials;
• Obtain script and install .NET CLI one-liner examples:
Windows:
# Run a separate PowerShell process because the script calls exit, so it will end the current PowerShell session.
&powershell -NoProfile -ExecutionPolicy unrestricted -Command "[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12; &([scriptblock]::Create((Invoke-WebRequest -UseBasicParsing 'https://dot.net/v1/dotnet-install.ps1'))) <additional install-script args>"
macOS/Linux:
curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin <additional install-script args>
