Automation api with (un)packaged winui3 app not working

[Gitii]

Hi,

I try to add end to end tests to my project.
It's a winui3 app that is packaged by default.
When using inspect, the element DesktopChildSiteBridge has no children and thus I cannot use the automation api to write tests using appium.
I also tried it with an unpackaged version of my app.
This time, whenever inspect is running my app freezes after startup and then crashes.
Strangly debugging in Visual Studio "prevents" a crash but DesktopChildSiteBridge is still empty.

So does winui3 / windowsappsdk 1.X.X support the automation api?
Or have I done anything wrong?

Best regards,

Gitii

It works for me with random controls :
(Windows 10 21H1 (french), Windows App SDK 1.1.0, Unpackaged, C#, test with Inspect x64)

Thanks for your test run, @castorix !
I already assumed that it might be something in my app that breaks the automation api.
Thing is that I have no idea why 🤷‍♂️
Does it work for you when it's packaged?

Yes, no difference.

Thanks, I was able to solve the issue:
The main thread wasn't a STA thread.
