Add Support for installing NuGet Packages

[adam-birds-test]

Manage NuGet Packages is greyed out and doesn't let you install them when developing a project in Powershell Pro Tools.

Specifically the one I want to use is the below to add more functionality to WPF.:

https://www.nuget.org/packages/Extended.Wpf.Toolkit/

This is the error I get when I right click the project and click Manage NuGet Packages.

@adamdriscoll any update on this?

This requires an update to the NuGet package manager and it's not something I can control with PoshTools. :(

In the absence of being able to use nuget or dotnet to install these packages, do you know how to get the extended wpf toolkit working within a project.

I have got the DLL for it, created a reference for it in the project.

I have also added the below to the .xaml file:

xmlns:xctk="clr-namespace:Xceed.Wpf.Toolkit;assembly=Xceed.Wpf.Toolkit"

But when running the project I get the below error:

[ERROR] Exception calling "Load" with "1" argument(s): "Cannot create unknown type '{clr-namespace:Xceed.Wpf.Toolkit;assembly=Xceed.Wpf.Toolkit}DateTimePicker'."
[ERROR] At C:\SCRIPTS\HWT Tools - Github\script-user-creation-tool\User-Creation-Tool\User-Creation-Tool\Forms\MainScreen.xaml.ps1:9 char:2
[ERROR] +     [Windows.Markup.XamlReader]::Load($XamlReader)
[ERROR] +     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[ERROR]     + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
[ERROR]     + FullyQualifiedErrorId : XamlParseException
[ERROR]  

My .xaml.ps1 file is as below:

Function Load-Xaml {
	[xml]$Xaml = Get-Content -Path $PSScriptRoot\MainScreen.xaml
	$Manager = New-Object System.Xml.XmlNamespaceManager -ArgumentList $Xaml.NameTable
	$Manager.AddNamespace("x", "http://schemas.microsoft.com/winfx/2006/xaml");
	$Manager.AddNamespace("xctk", "clr-namespace:Xceed.Wpf.Toolkit;assembly=Xceed.Wpf.Toolkit");
	$XamlReader = New-Object System.Xml.XmlNodeReader $Xaml
	[Windows.Markup.XamlReader]::Load($XamlReader)
}

$MainScreenWindow = Load-Xaml

I tried adding the $Manager.AddNamespace("xctk", "clr-namespace:Xceed.Wpf.Toolkit;assembly=Xceed.Wpf.Toolkit"); line to solve the issue, but I get the same error. Any ideas how to use these custom wpf namespaces in these projects?
