-.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-    This parameter is obsolete and may be removed in a future version of this script.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'.
-    Installs just the shared runtime bits, not the entire SDK.
-.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
-        - windowsdesktop - the Microsoft.WindowsDesktop.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 ProxyBypassList
-    If set with ProxyAddress, will provide the list of comma separated urls that will bypass the proxy
-.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.
-.PARAMETER JSonFile
-    Determines the SDK version from a user specified global.json file
-    Note: global.json must have a value for 'SDK:Version'
