How to use a NuGet package within a PowerShell scr

I'm writing a PowerShell script that makes use of the Mono.Cecil library. How would I install the package so I can use it from within the script? Thanks!

(For the record, I did try Googling before asking this, but all that came up was results about PMC and Visual Studio, which aren't relevant to this question.)

I was able to install a package in PowerShell 6 (Core) by specifying the source:

PS > install-package gudusoft.gsqlparser -source https://www.nuget.org/api/v2

~5.x versions of PowerShell have a nuget package source included by default but it doesn't work:

PS > Get-PackageSource 
Name                             ProviderName     IsTrusted  Location
----                             ------------     ---------  --------
nuget.org                        NuGet            False      https://api.nuget.org/v3/index.json
PSGallery                        PowerShellGet    False      https://www.powershellgallery.com/api/v2/

If you Unregister-PackageSource -Source nuget.org and Register-PackageSource -Location https://www.nuget.org/api/v2 -name nuget.org -Trusted I have been able to install nuget papckages with just Install-Package from PowerShell, not within visual studio. Got the idea from this SO answer.

I don't know what other possible negative impacts there are to removing the v3 version of the nuget.org source but I have been running this way for a while and things appear ok, your mileage may vary.

As an alternative here is an example that gets the job done by pulling down the nuget.exe even if it is a crummy way to have to do this:

function Install-InvokeOracleSQL {
    $ModulePath = (Get-Module -ListAvailable InvokeSQL).ModuleBase
    Set-Location -Path $ModulePath

    if ($PSVersionTable.Platform -ne "Unix") {
        $SourceNugetExe = "https://dist.nuget.org/win-x86-commandline/latest/nuget.exe"
        $TargetNugetExe = ".\nuget.exe"
        Invoke-WebRequest $sourceNugetExe -OutFile $targetNugetExe
        .\nuget.exe install Oracle.ManagedDataAccess
        Remove-Item -Path $TargetNugetExe
    } elseif ($PSVersionTable.Platform -eq "Unix") {
        nuget install Oracle.ManagedDataAccess.Core -Version 2.12.0-beta2
    }
}

Unable to find a good solution, I ended up just downloading and unzipping the package manually via the NuGet API.

For those who are interested/others who have this problem, here is the code I used.
