ArgumentNullException in TeeChart.Maui.Gallery

[taimo42]

Hi,
I'm having trouble when trying out the Maui example for the TeeChart control.
Here are the details:

Development Environment

• Microsoft Windows 10 Pro, Version 21H2, OS build 19044.2130
• Microsoft Visual Studio Professional 2022 (64-bit) - Version 17.3.6

Steps to reproduce

• Download this repository
• Open 'TeeChart-NET-Pro-Samples-main\MAUI\TeeChart.Maui.Gallery\TeeChart.Maui.Gallery.sln' in Visual Studio
• Select 'Windows Machine' as the target
• Build and Run the solution

Result

System.ArgumentNullException
HResult=0x80004003
Message=Value cannot be null. (Parameter 'type')
Source=System.Private.CoreLib
StackTrace:
at System.Activator.CreateInstance(Type type, BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes)
at Steema.TeeChart.Drawing.Shape.get_Pen()
at Steema.TeeChart.Panel..ctor(Chart c)
at Steema.TeeChart.Chart.InitVars()
at TeeChart.Maui.ChartView..ctor()
at TeeChart.Maui.Gallery.MainPage.OnCounterClicked(Object sender, EventArgs e) in .....\TeeChart-NET-Pro-Samples-main\MAUI\TeeChart.Maui.Gallery\MainPage.xaml.cs:line 25
at TeeChart.Maui.Gallery.MainPage..ctor() in .....\TeeChart-NET-Pro-Samples-main\MAUI\TeeChart.Maui.Gallery\MainPage.xaml.cs:line 11
at System.RuntimeType.CreateInstanceDefaultCtor(Boolean publicOnly, Boolean wrapExceptions)

Can someone help me make this working?

Yes, the TeeChart for MAUI Windows platform part still giving some problems. For the moment only the other platforms (Android, iOS and MacOS) are available.
We hope to have working on Windows plarform shortly.
Thanks.
