Avalonia Can't find Package

I am trying to implement LiveCharts2 into my project, but keep getting compile errors form the XAML file saying “Unable to resolve type PieChart from namespace using:LiveChartsCore.SkiaSharpView.Avalonia”. The program will run, but it doesn’t display the graphs. I installed LiveCharts from the Package manager console using this line: “Install-Package LiveChartsCore.SkiaSharpView.Avalonia -Version 2.0.0-beta.300”

I set up my view like this:

<UserControl xmlns="https://github.com/avaloniaui"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             mc:Ignorable="d"
             xmlns:lv="clr-namespace:LiveChartsCore;assembly=LiveChartsCore"
             xmlns:lvc="using:LiveChartsCore.SkiaSharpView.Avalonia"
             x:Class="PowderInventory.InventoryManagement.UI.Views.OperatorView">
	<StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
		<TextBlock Text="Hi, this is the operator view" />
		<TextBlock Text="{Binding UrlPathSegment}" />
		
		<lvc:PieChart Series="{Binding Series}" LegendPosition="Right"/>
	</StackPanel>
</UserControl>

and my ViewModel uses the Series data from the sample

public IEnumerable<ISeries> Series { get; set; } = new ISeries[]
         {
             new PieSeries<double> { Values = new double[] { 2 }, Name = "Slice 1" },
             new PieSeries<double> { Values = new double[] { 4 }, Name = "Slice 2" },
             new PieSeries<double> { Values = new double[] { 1 }, Name = "Slice 3" },
             new PieSeries<double> { Values = new double[] { 4 }, Name = "Slice 4" },
             new PieSeries<double> { Values = new double[] { 3 }, Name = "Slice 5" }
         };

Hi. I also was having this issue. CartesianChart was working, but it wasn’t showing on designer preview. I added this to Program.cs in BuildAvaloniaApp method.

GC.KeepAlive(typeof(LiveChartsCore.SkiaSharpView.Avalonia.CartesianChart).Assembly);
