.SYNOPSIS
    Installs dependencies required to build and test the projects in this repository.
.DESCRIPTION
    This MAY not require elevation, as the SDK and runtimes are installed to a per-user location,
    unless the `-InstallLocality` switch is specified directing to a per-repo or per-machine location.
    See detailed help on that switch for more information.

    The CmdEnvScriptPath environment variable may be optionally set to a path to a cmd shell script to be created (or appended to if it already exists) that will set the environment variables in cmd.exe that are set within the PowerShell environment.
    This is used by init.cmd in order to reapply any new environment variables to the parent cmd.exe process that were set in the powershell child process.
.PARAMETER InstallLocality
    A value indicating whether dependencies should be installed locally to the repo or at a per-user location.
    Per-user allows sharing the installed dependencies across repositories and allows use of a shared expanded package cache.
    Visual Studio will only notice and use these SDKs/runtimes if VS is launched from the environment that runs this script.
    Per-repo allows for high isolation, allowing for a more precise recreation of the environment within an Azure Pipelines build.
    When using 'repo', environment variables are set to cause the locally installed dotnet SDK to be used.
    Per-repo can lead to file locking issues when dotnet.exe is left running as a build server and can be mitigated by running `dotnet build-server shutdown`.
    Per-machine requires elevation and will download and install all SDKs and runtimes to machine-wide locations so all applications can find it.
.PARAMETER NoPrerequisites
    Skips the installation of prerequisite software (e.g. SDKs, tools).
.PARAMETER NoNuGetCredProvider
    Skips the installation of the NuGet credential provider. Useful in pipelines with the `NuGetAuthenticate` task, as a workaround for https://github.com/microsoft/artifacts-credprovider/issues/244.
    This switch is ignored and installation is skipped when -NoPrerequisites is specified.
.PARAMETER UpgradePrerequisites
    Takes time to install prerequisites even if they are already present in case they need to be upgraded.
    No effect if -NoPrerequisites is specified.
.PARAMETER NoRestore
    Skips the package restore step.
.PARAMETER Signing
    Install the MicroBuild signing plugin for building test-signed builds on desktop machines.
.PARAMETER Localization
    Install the MicroBuild localization plugin for building loc builds on desktop machines.
    The environment is configured to build pseudo-loc for JPN only, but may be used to build
    all languages with shipping-style loc by using the `/p:loctype=full,loclanguages=vs`
    when building.
.PARAMETER Setup
    Install the MicroBuild setup plugin for building VSIXv3 packages.
.PARAMETER OptProf
    Install the MicroBuild OptProf plugin for building optimized assemblies on desktop machines.
.PARAMETER AccessToken
    An optional access token for authenticating to Azure Artifacts authenticated feeds.
