Version 1.1.1 cause exception when binding keyboard accelerator invoked event

[EFLKumo]

My code (unnecessary parts had been omitted):

using Microsoft.UI.Xaml.Input;
using Windows.System;
// ...
KeyboardAccelerator _altLeftKeyboardAccelerator = BuildKeyboardAccelerator(VirtualKey.Left, VirtualKeyModifiers.Menu);
// ...
KeyboardAccelerator BuildKeyboardAccelerator(VirtualKey key, VirtualKeyModifiers? modifiers = null)
{
    var keyboardAccelerator = new KeyboardAccelerator() { Key = key };
    if (modifiers.HasValue)
    {
        keyboardAccelerator.Modifiers = modifiers.Value;
    }

    keyboardAccelerator.Invoked += OnKeyboardAcceleratorInvoked;
    return keyboardAccelerator;
}

void OnKeyboardAcceleratorInvoked(KeyboardAccelerator sender, KeyboardAcceleratorInvokedEventArgs args)
{
    var navigationService = App.GetService<INavigationService>();
    var result = navigationService.GoBack();
    args.Handled = result;
}

It will cause System.MissingMethodException at the line keyboardAccelerator.Invoked += OnKeyboardAcceleratorInvoked;
and here is the information:

System.MissingMethodException:“Method not found: 'WinRT.ObjectReferenceValue ABI.Windows.Foundation.TypedEventHandler`2.CreateMarshaler2(Windows.Foundation.TypedEventHandler`2<!0,!1>)'.”

Actually, code above was generated by Microsoft/TemplateStudio and it worked well before. After I updated Windows App SDK (from 1.0) to 1.1.1, it threw the exception. Does anyone know why? It's just confusing!

@RayGicEFL Can I get you to try manually deleting your bin and obj folders of your app and then rebuilding and try again. Let me know if that helps or not.

Thanks, I'll try if I have time. I did sth like that before, to fix a foolish problem (InitializeComponent() method not found) and it worked, so I suspect there is same cause between the two problems.

The problem still exists after I deleted bin and obj folders manually. I tried to delete all the codes about keyboard accelerator, then I got XAMLParseException:

   at MYPROJECT.Views.ShellPage..ctor(ShellViewModel viewModel) in ***\Views\ShellPage.xaml.cs:line 27

I checked ShellPage.g.i.cs:line45:

global::Microsoft.UI.Xaml.Application.LoadComponent(this, resourceLocator, global::Microsoft.UI.Xaml.Controls.Primitives.ComponentResourceLocation.Application);

and ShellPage.xaml.cs:line27:

InitializeComponent();

which may be useless.

I continued to run my program and got more and more exception.

In fact, App.xaml.cs:line94 calls ActivationService.cs:line38 calls App.xaml.cs:line74. The operator is to load ShellPage. I suspect that ShellPage still has MissingMethodException because I saw MissingMethodException again in my VS IDE warnings below.
But remember that I deleted all the codes about keyboard accelerator.

Caused exception:“System.MissingMethodException”(at Microsoft.WinUI.dll)
Caused exception:“Microsoft.UI.Xaml.Markup.XamlParseException”(at WinRT.Runtime.dll)
WinRT Information: Method not found: 'WinRT.ObjectReferenceValue ABI.Windows.Foundation.TypedEventHandler`2.CreateMarshaler2(Windows.Foundation.TypedEventHandler`2<!0,!1>)'.

Caused exception:“Microsoft.UI.Xaml.Markup.XamlParseException”(at System.Private.CoreLib.dll)

“Microsoft.UI.Xaml.Markup.XamlParseException” exception at System.Private.CoreLib.dll，but is not processed in user code
WinRT Information: Method not found: 'WinRT.ObjectReferenceValue ABI.Windows.Foundation.TypedEventHandler`2.CreateMarshaler2(Windows.Foundation.TypedEventHandler`2<!0,!1>)'.
XAML parsing failed.

The reason I thought MissingMethodException was caused by codes about keyboard accelerator is, the description,

WinRT.ObjectReferenceValue ABI.Windows.Foundation.TypedEventHandler`2.CreateMarshaler2(Windows.Foundation.TypedEventHandler`2<!0,!1>)

is similar to:

keyboardAccelerator.Invoked += OnKeyboardAcceleratorInvoked;

in my code. keyboardAccelerator is Windows.Foundation.TypedEventHandler<KeyboardAccelerator, KeyboardAcceleratorInvokedEventArgs> and OnKeyboardAcceleratorInvoked is the function like void OnKeyboardAcceleratorInvoked(KeyboardAccelerator, KeyboardAcceleratorInvokedEventArgs)

However, the problem was solved by rebuilding project with Template Studio 5.1 (not 5.0).
