Overview

This document/spec outlines the CLI install experience. This covers the technologies being used for install, the principles that are driving the installation experience, the ways users are coming to the installs and what each of the installs contains, in terms of stability and similar.

General principles

Upgrades using the native installers Just Work(tm)
All user facing materials point to the getting started page
Defaults are stable bits; users need extra effort to install Future builds
Only HTTPS links are allowed in any online property
Provide native installers for each supported platform
Provide automation-ready installers for each target platform

Components that can be installed

Overall, there are two significant installable components:

The .NET Core SDK
Shared runtime redistributable

The .NET Core SDK contains the following items:

A given version of the CLI toolset - "SDK"
A given version of the shared runtime - "redist" - this will be consumed by both end-customers and CLI toolset
A given version of the shared host - "muxer" - shared component that is in charge of running the applications and the CLI commands - it should be treated as an implementation detail

Installation process

Each of the components listed in the previous section will have an installer/package. The dependencies of the installers between themseslves are given in the table below.

Installer	Depends on
SDK	redist
redist	muxer
muxer	-

The installation process will depend on the platform and the way of the install. For those installers that don't have automatic dependency resolution (Windows installer, OS X PKG) the installers will chain the installers of the components they depend on. DEB, RPM and similar will declare proper dependencies and the package manager will do the Right Thing(tm) by default.

From the table, we can see that if you install the SDK using apt-get for instance, you will get also a redist and a muxer. They will be separate packages, but will be declared as dependencies (similar for yum). Similar for the redist package.

The muxer is slightly a special case. Though there will be an installer, as mentioned in the previous section, it is an implementation detail. That means that acquiring the muxer should be done through either the SDK or the shared runtime installers. The only situation where this rule would not be true is if there was a major servicing event (e.g. a security update); in that case, the users would use the installer for the muxer directly, as we would rev its version accordingly.

The script installers are slightly different as they operate on zips/tarballs. The zip/tarball for the SDK will contain the entire set of things needed to be put on the disk.

Removal process

Removing the bits from the machine must follow the order outlined above in installation. If the SDK is installed, it needs to be removed first and then the Redist and only then the muxer. Similar for the Redist.

Upgrading the CLI

The semantics of installing the CLI will be side-by-side by default. This means that each new version will get installed besides any existing versions on disk. The layout section covers how that will look like on disk.

Since this is the case, there is no special "upgrade". When the user needs a new version, the user just installs the new version using any of the installers specified in this document. The installer will just drop a new version at the predefined location.

This, however, does have one specific constraint: newer versions must be installed in the same location the previous version was in. This constraint is due to the fact that the "muxer" uses convention to figure out how to find the actual driver that the user reuqested.

Layout on disk

<INSTALL_DIR>/ (%PATH%)
    dotnet ("muxer", has platform dependant file extension)
    hostfxr (implementation detail for "muxer", platform dependant file extension)
    sdk/
        <sdk-version-0>/ (i.e. "1.0.0-rc2-002543")
            ... (binaries like: dotnet.dll, csc.dll)
        <sdk-version-1>/
            ... (binaries)
        ...
    shared/ ("redist" or "shared framework")
        <target-framework-name>/ (currently only "Microsoft.NETCore.App")
            <redist-version-0>/ (i.e. "1.0.0-rc2-3002543")
                ... (binaries like: coreclr.dll, mscorlib.ni.dll, System.*.dll, dotnet-hostimpl.dll, dotnet, netcoreapp.deps.json)
            <redist-version-1>/
                ... (binaries)

Native dependencies

.NET Core CLI is built on top of CoreFX and CoreCLR and as such its' dependencies set is defined by the platform that those two combine. Whether or not those dependencies will be installed depends on the installer being used. The table below lists out the installers and whether or not they bring in dependencies.

Installer	Dependencies Y/N
EXE	Y (chains them in)
PKG	N (need to be manually installed*)
apt-get	Y
rpm	Y

* PKG cannot specify and automatically install native dependencies

A list of dependencies can be found on dependency list.

Channels

Channels represent a way for users who are getting the CLI to reason about the stability and quality of the bits they are getting. This is one more way for the user to be fully aware of the state the bits that are being installed are in and to set proper expectations on first use.

Channel	Description
LTS	Latest long-term supported release.
Current	Most current release - typically 'preview' releases.

Funnels and discovery mechanisms for CLI bits

There are multiple ways that we will funnel users towards the installers for the CLI:

Getting Started Page
Repo landing page
Package repositories for platforms (apt-get, brew etc.)
IDEs and editors that integrate with CLI (e.g. Visual Studio, VS Code, Sublime etc.)

Out of the above, the first two funnels are under the control of the CLI team so we will go into slightly more details. The rest of the funnels will use a prescribed way to get to the bits and will have guidance on what bits to use.

Getting Started page

The page can be found on https://aka.ms/dotnetcoregs. This is the main curated first-run funnel for the dotnet CLI. The intent of the page is to help users test out the CLI quickly and become familiar with what the platform offers. This should be the most stable and curated experience we can offer.

The Getting Started page should only point users to curated install experiences that can contain only stable or LKG bits.

The below table shows other pertinent information for installs on the "Getting started" page.

Property	Description
Debian feed	Development
Brew repo/tap	Brew binary repo (https://github.com/Homebrew/homebrew-binary)
CentOS feed	TBD

Repo landing page

The repo landing page can be found on: Repo landing page. Download links on the landing page should be decreased in importance. First thing for "you want to get started" section should link to the getting started page on the marketing site. The Repo Landing Page should be used primarily by contributors to the CLI. There should be a separate page that has instructions on how to install both the latest stable as well as latest development with proper warnings around it. The separate page is to really avoid the situation from people accidentally installing unstable bits (since search engines can drop them in the repo first).

The source branches and other items are actually branch specific for the repo landing page. As the user switches branches, the links and badges on the page will change to reflect the builds from that branch.

Acquisition modes

There are multiple acquisition modes that the CLI will have:

Native installers
Install scripts
NuGet packages (for use in other people's commands/code)
Docker

Let's dig into some details.

Native installers

These installation experiences are the primary way new users are getting the bits. The primary way to get information about this mode of installation is the Getting Started page. The native installers are considered to be stable by default; this does not imply lack of bugs, but it does imply predictable behavior. They are generated from the stable branches and are never used to get the Future bits.

There are three main components that will be installed

The native installers are:

Platform	Installer	Status	Package name
Windows	Bundle installer	Done	dotnet-{version};
Ubuntu 14.04/Debian	apt-get feed	Done	dotnet; dotnet-dbg
OS X	PKG	Done	dotnet
OS X	Homebrew	Not done	dotnet
CentOS/RH	RPM	Not done	dotnet

Installation script

This approach is a shell one-liner that downloads an installation script and runs it. The installation script will download the latest zip/tarball (depending on the script used) and will unpack it to a given location. After that, the script will print out what needs to be set for the entire CLI to work (env variables, $PATH modification etc.).

This install covers the following main scenario:

Local installation on a dev machine
Acquiring tools on a CI build server

The features the script needs to support/have are:

Support for specifying the channel
Support for specifying the version
Support for specifying the installation location
Automatically add the install to $PATH unless --no-path/-NoPath is present

It is recommended to use the stable version that is hosted on .NET Core main website. The direct path to the scripts are:

https://dot.net/v1/dotnet-install.sh (bash, UNIX)
https://dot.net/v1/dotnet-install.ps1 (powershell, Windows)

Installation script features

The following arguments are needed for the installation script:

dotnet-install.sh arg (Linux, OSX)	dotnet-install.ps1 arg (Windows)	Defaults	Description
--channel	-Channel	"LTS"	Which channel (i.e. "LTS", "Current", "1.0", "2.0", etc) to install from.
--version	-Version	Latest	Which version of CLI to install; you need to specify the version as 3-part version (i.e. 1.0.0-13232). The 'version' parameter supersedes the 'channel' parameter.
--install-dir	-InstallDir	.dotnet	Path to where to install the CLI bundle. The directory is created if it doesn't exist. On Linux/OSX this directory is created in the user home directory (`$HOME`). On Windows, this directory is created in `%LocalAppData%`.
--no-path	-NoPath	false	Do not export the installdir to the path for the current session. This makes CLI tools available immediately after install.
--shared-runtime	-SharedRuntime	false	Install just the shared runtime bits, not the entire SDK.
--architecture	-Architecture	Current OS (`<auto>`)	Architecture to install. The possible values are `<auto>`, `x64` and `x86`.
--dry-run	-DryRun	false	If set, it will not perform the installation but will show, on standard output, what the invocation of the script will do with the options selected.
--verbose	-Verbose	false	Display diagnostic information.
N/A	-ProxyAddress	""	If set, the installer will use the specified proxy server for all of its invocations.

Note: Powershell arg naming convention is supported on Windows and non-Windows platforms. Non-Windows platforms do additionally support convention specific to their platform.

Install the 1.1.0 of the shared runtime

Windows:

./dotnet-install.ps1 -SharedRuntime -Version 1.1.0

macOS/Linux:

./dotnet-install.sh --shared-runtime --version 1.1.0

Install the latest supported CLI

Windows:

./dotnet-install.ps1 -Channel LTS

OSX/Linux:

./dotnet-install.sh --channel LTS

Install the latest CLI to specified location

Windows:

./dotnet-install.ps1 -Channel Current -InstallDir C:\cli

OSX/Linux:

./dotnet-install.sh --channel Current --install-dir ~/cli

Install the latest CLI in the 2.0 channel

Windows:

./dotnet-install.ps1 -Channel 2.0

OSX/Linux:

./dotnet-install.sh --channel 2.0

Windows obtain one-liner example

@powershell -NoProfile -ExecutionPolicy unrestricted -Command "&([scriptblock]::Create((Invoke-WebRequest -useb 'https://dot.net/v1/dotnet-install.ps1'))) <additional installation-script args>"

OSX/Linux obtain one-liner

curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin <additional installation-script args>

Docker

Docker has become a pretty good way to use developer tools, from trying them out in an interactive image use to using it for deployment. We have Docker images on DockerHub already.

Docker images should always be updated as we make new releases. We should have Docker images of stable releases, built from the release branches.

NuGet packages

NuGet packages of the CLI bits that make sense are published to relevant feeds. The developer who wishes to use these needs to specify a version. The actual "installation" here is restoring the package as a dependency for a certain project (i.e. ProjectServer or similar).

Acquiring through other products

IDEs and editors

Anything that goes into the higher-level tools should always use a stable build of CLI coming frol release branches as required.

If there exist any mechanism that notifies users of updates of the CLI, it should ideally point users to the Getting Started page to acquire the installers, or, if that is deemed too heavy-handed, it should point people to the last stable release. If there is a need of the URL to be "baked in" to the higher-level tool, that URL should be an aka.ms URL because it needs to be stable on that end.

Cross-platform IDEs/editors will work in similar way as above. The notification should also point people to the Getting Started page. The reason is simple: it is the one page where users can pick and choose their installation experience.

Visual Studio

Visual Studio will not be shipping CLI in-box. However, it will use CLI when installed. The install will be tied into other installs like WET and similar. The URL that is baked in VS should be an aka.ms URL or other stable URL/location.

Detecting dotnet/cli installation

Windows

Requirements for CLI SDK and shared framework installer

Support side by side installation and can be compatible with older versions of themselves
Supports removing of any side by side version
Prerelease versions are compatible only with the same prerelease versions

Scenarios

Installing the product produces registry value informing about full version of the product which is being installed
Installing the product produces registry values informing about compatible versions of the products
Removing the product removes the registry keys if none of the versions of the product is supporting the given version. Specifically at least one registry key with full version should be removed.
Installing older version of the product is possible

Registry keys and values

Full version refers to NuGet semantic version which contains the build number
Version refers to NuGet semantic version which does not contain build number

Registry key should be created under following path:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\dotnet\Setup\InstalledVersions\<platform>\<installer-name>\[REG_DWORD]<nuget-version>=1

<platform>=(x86|x64) <installer-name>=(sdk|sharedfx)

Example output (installing CLI SDK x86 with version 1.0.3-123456):

HKLM\SOFTWARE\WOW6432Node\dotnet\Setup\InstalledVersions\x86\sdk\[REG_DWORD]1.0.0=1
HKLM\SOFTWARE\WOW6432Node\dotnet\Setup\InstalledVersions\x86\sdk\[REG_DWORD]1.0.1=1
HKLM\SOFTWARE\WOW6432Node\dotnet\Setup\InstalledVersions\x86\sdk\[REG_DWORD]1.0.2=1
HKLM\SOFTWARE\WOW6432Node\dotnet\Setup\InstalledVersions\x86\sdk\[REG_DWORD]1.0.3=1
HKLM\SOFTWARE\WOW6432Node\dotnet\Setup\InstalledVersions\x86\sdk\[REG_DWORD]1.0.3-123456=1

Note: 1.0.3 has two entries

Explanation: CLI SDK version 1.0.3-123456 is compatible with any build of 1.0.3, 1.0.2, 1.0.1 and 1.0.0. If another installer is trying to find if there exists CLI SDK which supports specific version of installer they can check for presence of the value 1 under the registry path.

Requirements for shared host installer

Supports only in-place updated and is assumed to be always compatible with older versions of itself

Scenarios

Installing the product produces one registry value containing the latest version
Installing older version on top of the other is not possible
Removing removes the product completely with its registry keys, regardless of any previous installations

Registry key should be created under following path:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\dotnet\Setup\InstalledVersions\<platform>\[REG_SZ]sharedhost=<nuget-semversion>

Example

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\dotnet\Setup\x64\[REG_SZ]sharedhost=1.0.0-rc2-123456

Other Examples

Operations: NOP - key already existed, do nothing with it ADD - add DEL - delete RF+ - not adding because key already exist (installer will increse ref count on GUID related to this value) RF- - not deleting because something else is compatible with this (decrease ref count)

Scenario 1

Installing 1.0.3-123456 (RTM) to a clean machine

Note: Installer is compatible with all previous versions and all their RCs.
