[MAUI] [WinUI] App crashes when using the startup task ability

ITaluone commented 6 months ago

Description

If I configure my maui app to run as a startup task like this:

<desktop:Extension Category="windows.startupTask" Executable="MyApp.exe"
    EntryPoint="Windows.FullTrustApplication">
    <desktop:StartupTask TaskId="my.applicationId.from.csproj" Enabled="true"
        DisplayName="My App" />
</desktop:Extension>

where the desktop xml namespace is: xmlns:desktop="http://schemas.microsoft.com/appx/manifest/desktop/windows10" and my.applicationId.from.csproj matches this <ApplicationId>my.applicationId.from.csproj</ApplicationId>

I am able to enable this app as startup task in windows app settings. So far so good..

Now, if I logoff and back on I run into following error: My App shows up for like 100ms and then crashes silently. Only two messages in the event log are added.

First event log:

Application: MyApp.exe
CoreCLR Version: 8.0.324.11423
.NET Version: 8.0.3
Description: The process was terminated due to an unhandled exception.
Exception Info: System.Runtime.InteropServices.COMException (0x80040154)

   at ABI.Microsoft.UI.Xaml.IApplicationStaticsMethods.Start(IObjectReference _obj, ApplicationInitializationCallback callback)
   at MyApp.WinUI.Program.Main(String[] args)

Second event log in german:

Unfortunately I cannot give any more information, because everything is working when:

Starting the same installed app manually (e.g. search in windows menu and click it)
Starting the same installed app with a defined appExecutionAlias with a link inside shell:startup

This config looks like this:

<uap5:Extension Category="windows.appExecutionAlias" Executable="MyApp.exe"
    EntryPoint="Windows.FullTrustApplication">
    <uap5:AppExecutionAlias>
        <uap5:ExecutionAlias Alias="MyAppAlias.exe" />
    </uap5:AppExecutionAlias>
</uap5:Extension>

where namespace uap5 is xmlns:uap5="http://schemas.microsoft.com/appx/manifest/uap/windows10/5"

Starting the app from VS (with or without debugging and with configuration debug or release)

This looks like something that can be relatively easily tested in a vanilla[^1] WinUI (without MAUI) to find out if it is a MAUI bug or a WinUI bug.

[^1]: I use my testing app https://github.com/MartyIX/LineHeight202404/.

Now I am confused completely... I have to admit, that my app has some special cases which should be met.

SingleInstanceApp
Unable to close (on minimize and/or closing the window it moves complete out of the way into the system tray)
Open on tel: links (or more in common: binds to protocols)
should start hidden on windows logon
app notification
and so on...

So I decided to test this with a boilerplate VS MAUI-Blazor, just adding the capability for startupTask... and... it works. After this insight, I was sure it have to be one or more piece of aforementioned app capabilities, so I removed anything special to my app.. and it worked. Now, after quite a long iteration between: "Adding something back" -> "publish" -> "install the msix" -> "repeat" I am now in the initial state.. Error: gone 🤷‍♂️

Can anybody relate to this? 😆

Hmm good to hear your unblocked @ITaluone

Can we close this issue for now? If you're able to reproduce this in a vanilla WinUI app then we can create an issue for them

ITaluone commented 6 months ago

Hmm good to hear your unblocked

Me too... But I did nothing different... suddenly it seems to work

Can we close this issue for now?

Yes I guess..

I will reopen if this problem comes back
