.SYNOPSIS
|
|
Installs dotnet cli
|
|
.DESCRIPTION
|
|
Installs dotnet cli. If dotnet installation already exists in the given directory
|
|
it will update it only if the requested version differs from the one already installed.
|
|
.PARAMETER Channel
|
|
Default: preview
|
|
Channel is the way of reasoning about stability and quality of dotnet. This parameter takes one of the values:
|
|
- future - Possibly unstable, frequently changing, may contain new finished and unfinished features
|
|
- preview - Pre-release stable with known issues and feature gaps
|
|
- production - Most stable releases
|
|
.PARAMETER Version
|
|
Default: latest
|
|
Represents a build version on specific channel. Possible values:
|
|
- 4-part version in a format A.B.C.D - represents specific version of build
|
|
- latest - most latest build on specific channel
|
|
- lkg - last known good version on specific channel
|
|
Note: LKG work is in progress. Once the work is finished, this will become new default
|
|
.PARAMETER InstallDir
|
|
Default: %LocalAppData%\Microsoft\.dotnet
|
|
Path to where to install dotnet. Note that binaries will be placed directly in a given directory.
|
|
.PARAMETER Architecture
|
|
Default: <auto> - this value represents currently running OS architecture
|
|
Architecture of dotnet binaries to be installed.
|
|
Possible values are: <auto>, x64 and x86
|
|
.PARAMETER DebugSymbols
|
|
If set the installer will include symbols in the installation.
|
|
.PARAMETER DryRun
|
|
If set it will not perform installation but instead display what command line to use to consistently install
|
|
currently requested version of dotnet cli. In example if you specify version 'latest' it will display a link
|
|
with specific version so that this command can be used deterministicly in a build script.
|
|
It also displays binaries location if you prefer to install or download it yourself.
|
|
.PARAMETER NoPath
|
|
By default this script will set environment variable PATH for the current process to the binaries folder inside installation folder.
|
|
If set it will display binaries location but not set any environment variable.
|
|
.PARAMETER Verbose
|
|
Displays diagnostics information.
|
|
.PARAMETER AzureFeed
|
|
Default: https://dotnetcli.blob.core.windows.net/dotnet
|
|
This parameter should not be usually changed by user. It allows to change URL for the Azure feed used by this installer.
