The project build but n debug it works but without debugging the login page is not opened.
I checked all nugets packages and moved to last.
================================
<ItemGroup>
<PackageReference Include="Microsoft.Maui.Controls" Version="$(MauiVersion)" />
<PackageReference Include="CommunityToolkit.Maui" Version="9.0.0" />
<PackageReference Include="System.Management" Version="9.0.1" />
<PackageReference Include="Telerik.UI.for.Maui" Version="8.0.0" />
<PackageReference Include="Microsoft.Extensions.Logging.Log4Net.AspNetCore" Version="8.0.0" />
<PackageReference Include="Autofac" Version="8.2.0" />
<PackageReference Include="DotNetZip" Version="1.16.0" />
</ItemGroup>
<!-- Windows -->
<ItemGroup Condition="$(TargetFramework.Contains('-windows')) == true">
<PackageReference Include="WindowsAPICodePack" Version="8.0.6" />
</ItemGroup>
This is my xaml.cs
===========
public partial class App : Application
{
private static Mutex mutex = new Mutex(true, Assembly.GetEntryAssembly().GetName().Name);
public App()
{
if (!mutex.WaitOne(TimeSpan.Zero, true))
{
Current.Quit();
Environment.Exit(0);
}
InitializeComponent();
MainPage = new LoginPage();
}
protected override Window CreateWindow(IActivationState? activationState)
{
Window window = base.CreateWindow(activationState);
try
{
window.Stopped += async(s,e) =>
{
if (!string.IsNullOrEmpty(LoginConfigurations.GetInstance().SessionToken ))
{
var container = new Bootstrapper().Bootstrap();
IAutomationApiClient automationApiClient = container.Resolve<IAutomationApiClient>();
var results = await automationApiClient.PostLogOut($"{LoginConfigurations.GetInstance().Portal}/api/GSPortal/PostLogOut/false", LoginConfigurations.GetInstance().SessionToken);
if(results)
{
App.Current.Quit();
}
}
};
}
catch (Exception)
{
}
return window;
}
}
}
How to solve the problem ?

Firstly, if you use the Telerik.UI.for.Maui.8.0.0 NuGet package and .NET 9, you must also install the Microsoft.Maui.Controls.Compatibility package
Or update your Telerik.UI.for.Maui to 9.0.0 from

typically this is caused by using a library that does not support AOT (uses reflection, etc):
https://learn.microsoft.com/en-us/dotnet/maui/deployment/nativeaot?view=net-maui-9.0
you can disable AOT. (I'd suspect autofac, and replace it with Services).
I disable autofac and still problem not solved,
Your quick answer will be appreciated

I check is not autofac. What could be the problem.
you can play with the trimming options:
https://learn.microsoft.com/en-us/dotnet/maui/deployment/trimming?view=net-maui-9.0
also libraries that generate proxy code (System.Reflection.Emit), will not work on IOS, as IOS does not allow self modifying code nor does AOT support it. this is why .net is changing to the compiler doing the emit, like with json serialization.
Hello,
