DisplayRootViewForAsync throws System.InvalidOperationException #894

Closed vugarli closed 8 months ago

vugarli commented 8 months ago

I setted up IoC container as instructed here.

Here is my CustomBootstrapper.cs:

public record Test(string name);

public class CustomBootstrapper : BootstrapperBase
{
    private SimpleContainer _container = new SimpleContainer();

    protected override object GetInstance(Type serviceType, string key)
    {
        return _container.GetInstance(serviceType, key);
    }

    protected override IEnumerable<object> GetAllInstances(Type serviceType)
    {
        return _container.GetAllInstances(serviceType);
    }

    protected override void BuildUp(object instance)
    {
        _container.BuildUp(instance);
    }

    protected override void Configure()
    {
        _container.Singleton<IWindowManager, WindowManager>();
        _container.Singleton<Test>();
        _container.Handler<Test>( (c) => new Test("aaa"));
        _container.RegisterPerRequest(typeof(ShellViewModel), null, typeof(ShellViewModel));
    }

    public CustomBootstrapper()
    {
        Initialize();
    }

    protected async override void OnStartup(object sender, StartupEventArgs e)
    {
        base.OnStartup(sender, e);
        await DisplayRootViewForAsync<ShellViewModel>();
    }

}

Call to DisplayRootViewForAsync() throws System.InvalidOperationException. Here is StackTrace:

It seems like there is more than one instance of ShellViewModel registered to IoC? Any ideas why this is happening or how to fix it?

I registered same type twice in Configure()
