What can we do ?

Kind of hesitate to suggest it but IMHO it should be fairly easy for you to debug your issue more in detail yourself using MAUI's sandbox project:

MediaPicker implementation for Windows is here: https://github.com/dotnet/maui/blob/main/src/Essentials/src/MediaPicker/MediaPicker.uwp.cs AFAIK.

I would check your issue more in detail but I don't have access to my dev machine at the moment.

PS: The other idea is to check if this part https://github.com/dotnet/maui/blob/main/src/Templates/src/templates/maui-mobile/Platforms/Windows/Package.appxmanifest#L42-L44 is correct and if you don't need some additional capability (given that it works with an admin account and not with an ordinary one).

This issue has been verified using Visual Studio 17.11.0 Preview 7.0(8.0.80). Can repro on Windows platform.

PauchardThomas commented 2 months ago

I was able to reproduce the issue on the maui Essentials.Sample project.

  1. Launch the project on Release
  2. Go to Media Picker Page
  3. Click on Capture Photo
  4. Nothing happened

Details :

https://github.com/dotnet/maui/blob/main/src/Essentials/src/MediaPicker/MediaPicker.uwp.cs

line 126 : 

var result = await WinLauncher.LaunchUriForResultsAsync(uri, options, set);`

=> result.Status value is LaunchUriStatus.Unknow then CaptureFileAsync method return null

What uri, options, and set are passed in?

MartyIX commented 2 months ago

Btw: I have found this workaround in a WinUI bug: https://github.com/microsoft/WindowsAppSDK/issues/1034#issuecomment-1456774014 and https://github.com/dotnet/maui/pull/13220 which implemented current code in MAUI.

There is also some proposal in WinAppSdk https://github.com/microsoft/WindowsAppSDK/pull/4576 for cameras.

I also launch my repro app (after installed msix) on a Windows 11 PC and it work on it ! Seems to be an OS issue (Windows 10 ?) to launch the Camera App....

My Windows 10 version :

Interesting find.

My Windows 10 version :

* (winver) : **22H2 (build 19045. 4651)**

* ((Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion').ReleaseId) **2009**

Hm, I can see that that OS will be supported only for another year here: https://learn.microsoft.com/en-us/lifecycle/announcements/windows-10-22h2-end-of-support-update and that it is the most up to date version of Windows 10. Hmmm.

I don't have a Windows 10 machine to test. Perhaps, it makes sense to ask here https://github.com/microsoft/microsoft-ui-xaml/discussions or directly in https://github.com/microsoft/WindowsAppSDK/issues/1034.

The only workaround that I found for now is to the implement the MediaCapture Class to create a camera view and create some buttons to take photo, retry and cancel...

For now i didn't found any workaround to open the Camera App.

Edit : A lib already exist : Camera.MAUI
