WinUI3 application is failed to start from command line

mimregit commented 9 months ago

Describe the bug

I created a sample application, there was nothing special, just do it with the wizard, named AppTest. The only modification was to add the appExecutionAlias extension to the package manifest file:

<Extensions>
    <uap5:Extension
      Category="windows.appExecutionAlias"
      Executable="AppTest.exe"
      EntryPoint="AppTest.App">
        <uap5:AppExecutionAlias>
            <uap5:ExecutionAlias Alias="AppTest.exe" />
        </uap5:AppExecutionAlias>
    </uap5:Extension>
</Extensions>

Started the app from the Visual Studio wroked well. Launched a command prompt, and typed in: AppTest

Weird results are:

The operating system starts 2 instances of the application, the first is suspended initially, the second runs, but turns into suspended mode in 3 seconds, then immediately closed.
There is no other effect on the screen.
There is a .NET Runtime error on the Event Viever, saying called a thread attached to an other thread: Application: AppTest.exe CoreCLR Version: 6.0.2724.6912 .NET Version: 6.0.27 Description: The process was terminated due to an unhandled exception. Exception Info: System.Runtime.InteropServices.COMException (0x8001010E): Az alkalmazás olyan objektumfelületet hívott, amely egy másik szálhoz volt rendelve.

The Application Object must initially be accessed from the multi-thread apartment. at WinRT.ExceptionHelpers.g__Throw|39_0(Int32 hr) at WinRT.ExceptionHelpers.ThrowExceptionForHR(Int32 hr) at ABI.Microsoft.UI.Xaml.IApplicationStaticsMethods.Start(IObjectReference _obj, ApplicationInitializationCallback callback) at Microsoft.UI.Xaml.Application.Start(ApplicationInitializationCallback callback) at AppTest.Program.Main(String[] args)

Please, Microsoft, this problem has a predecessor, and I found never a solution on any forum!

At this moment it is impossible to launch from command line any WinUI application, although it would be necessary. How can we solve this problem?

Steps to reproduce the bug

Create any WinUI app
Modify package.manifest
Run the app once
Open a command line and try to launch

Expected behavior

No response

NuGet package version

WinUI 3 - Windows App SDK 1.4.5: 1.4.240411001

I think you need to set your EntryPoint to "Windows.FullTrustApplication".
