.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: LTS
Download from the Channel specified. Possible values:
- Current - most current release
- LTS - most current supported release
- 2-part version in a format A.B - represents a specific release
examples: 2.0, 1.0
- Branch name
examples: release/2.0.0, Master
Note: The version parameter overrides the channel parameter.
.PARAMETER Version
Default: latest
Represents a build version on specific channel. Possible values:
- latest - most latest build on specific channel
- coherent - most latest coherent build on specific channel
coherent applies only to SDK downloads
- 3-part version in a format A.B.C - represents specific version of build
examples: 2.0.0-preview2-006120, 1.1.0
.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>, amd64, x64, x86, arm64, arm
.PARAMETER SharedRuntime
This parameter is obsolete and may be removed in a future version of this script.
The recommended alternative is '-Runtime dotnet'.
Default: false
Installs just the shared runtime bits, not the entire SDK.
This is equivalent to specifying `-Runtime dotnet`.
.PARAMETER Runtime
Installs just a shared runtime, not the entire SDK.
Possible values:
- dotnet - the Microsoft.NETCore.App shared runtime
- aspnetcore - the Microsoft.AspNetCore.App shared runtime
.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.azureedge.net/dotnet
This parameter typically is not changed by the user.
It allows changing the URL for the Azure feed used by this installer.
.PARAMETER UncachedFeed
This parameter typically is not changed by the user.
It allows changing the URL for the Uncached feed used by this installer.
.PARAMETER FeedCredential
Used as a query string to append to the Azure feed.
It allows changing the URL to use non-public blob storage accounts.
.PARAMETER ProxyAddress
If set, the installer will use the proxy when making web requests
.PARAMETER ProxyUseDefaultCredentials
Default: false
Use default credentials, when using proxy address.
.PARAMETER SkipNonVersionedFiles
Default: false
Skips installing non-versioned files if they already exist, such as dotnet.exe.
.PARAMETER NoCdn
Disable downloading from the Azure CDN, and use the uncached feed directly.
