I am working on a Maui App and want to add a graph, so I installed the Syncfusion.Maui.Charts NuGet Package. The issue is, in the code-behind I am getting the below error in my Frame where I have defined the graph;
Severity Code Description Project File Line Suppression State
Error (active) XFC0000 Cannot resolve type "clr-namespace:Syncfusion.Maui.Charts;assembly=Syncfusion.Maui.Charts:sfChart:BarSeries".

I can confirm that the Package does indeed appear under Dependencies in Solution Explorer and have tried uninstalling/reinstalling and deleting the bin and object folders and changing the namespace but nothing seems to work despite everything looking fine. I decided to do the basics and create a new, simple Project and installed the Syncfusion.Maui.Charts package, but same issue occurs despite how simple I have kept it. Below is the MainPage.xaml.cs;
using Syncfusion.Maui.Charts;
using Syncfusion.Maui.Core.Hosting;
namespace MauiApp1
{
public partial class MainPage : ContentPage
{
public ObservableCollection<SalesData> SalesDataCollection { get; set; }
public MainPage()
{
InitializeComponent();
SalesDataCollection = new ObservableCollection<SalesData>
{
new SalesData("Product A", 120),
new SalesData("Product B", 180),
new SalesData("Product C", 90),
};
BindingContext = this; // ✅ Set BindingContext
}
}
}
Below is the MainPage.xaml;
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:sfChart="clr-namespace:Syncfusion.Maui.Charts;assembly=Syncfusion.Maui.Charts"
x:Class="MauiApp1.MainPage">

XBindingPath="ProductName"
YBindingPath="SalesAmount"
ShowDataLabels="True"/>
</sfChart:SfCartesianChart.Series>
</sfChart:SfCartesianChart>
</VerticalStackLayout>
</ContentPage>
The error occurs at line 24 of the .xaml i.e. "<sfChart:BarSeries ItemsSource="{Binding SalesDataCollection}
"" on the 'sfChart:BarSeries' part.
The MauiProgram.cs file looks like this;
using Microsoft.Extensions.Logging;
using Syncfusion.Maui.Core.Hosting;
namespace MauiApp1
{
public static class MauiProgram
{
public static MauiApp CreateMauiApp()
{
var builder = MauiApp.CreateBuilder();
builder
.UseMauiApp<App>()
.ConfigureSyncfusionCore() // ✅ Ensure this line is added
.ConfigureFonts(fonts =>
{
fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
});
//builder.ConfigureSyncfusionCore(); // ✅ Register Syncfusion
#if DEBUG
builder.Logging.AddDebug();
#endif
return builder.Build();
}
}
}
For reference, the MauiApp1.csproj file looks like this;

I am completely stumped as to why I am getting this error. I have attached a screenshot of the Dependencies in Solution Explorer and can confirm that the package name appears under the Packages node of each .net8.0;
The error occurs at line 24 of the .xaml i.e. "<sfChart:BarSeries ItemsSource="{Binding SalesDataCollection}"" on the 'sfChart:BarSeries' part.
This is because there is no BarSeries
class in the Syncfusion.Maui.Charts. If you want to use BarChart, you can check the official sample about the BarChart.
<chart:SfCartesianChart IsTransposed="True">
<chart:SfCartesianChart.XAxes>
<chart:CategoryAxis/>
</chart:SfCartesianChart.XAxes>
<chart:SfCartesianChart.YAxes>
<chart:NumericalAxis/>
</chart:SfCartesianChart.YAxes>
<chart:ColumnSeries ItemsSource="{Binding Data}"
XBindingPath="XValue"
YBindingPath="YValue"/>
</chart:SfCartesianChart>
In addition, you can check all the Chart Types in the official doc.
