Bump nuspec file version with powershell

Bump Nuspec Version

Bumping the version of the nuspec file requires a little tweaking and I got some help from the slack powershell community to ensure I handled the xml parsing correctly. This was the result. If you are running a chocolatey package build or equivalent nuspec build via an agent and want a way to ensure the latest build updates the build version incrementally this should help.

This snippet should help give you a way to bump a nuspec file version programmatically.

    if ($null -eq $Directory)
    {
        throw "Cannot run interactively. Call file from prompt, as it needs PSScriptRoot variable to package"
    }
    # Update Version in Nuspec
    [string]$NuSpecFile = (Get-ChildItem -path $Directory -Filter *.nuspec | Select-Object -First 1).fullname
    [xml]$xml = Get-Content -path $NuSpecFile -Raw
    $ns = [System.Xml.XmlNamespaceManager]::new($xml.NameTable)
    $ns.AddNamespace('nuspec', 'http://schemas.microsoft.com/packaging/2015/06/nuspec.xsd')
    [version]$Version = [version]::parse($xml.SelectSingleNode('/nuspec:package/nuspec:metadata/nuspec:version', $ns).InnerText)
    [version]$NewVersion = [version]::new($Version.Major, $Version.Minor, ($Version.Build + 1))
    $xml.SelectSingleNode('/nuspec:package/nuspec:metadata/nuspec:version', $ns).InnerText = $NewVersion.ToString()
    $xml.SelectSingleNode('/nuspec:package/nuspec:metadata/nuspec:description', $ns).InnerText = Get-Content -Raw (Join-Path $Directory 'ReadMe.md')

    if ($PSCmdlet.ShouldProcess($NuSpecFile, "Version: $($Version.ToString()) bumped to $($NewVersion.ToString()) and file saved"))
    {
        $xml.Save($NuSpecFile)
        Write-PSFMessage -Level Important -Message "$NuSpecFile -- Original Version: $Version -- Updated to $NewVersion"
    }
}
catch
{
    throw
}

I modified the logic to support -WhatIf since I’m a fan of being able to run stuff like this without actually breaking things first.
