UWP to WinUI3 upgrade: System.InvalidOperationException: Sequence contains no elements

[myokeeh]

Describe the bug

I'm trying out the UWP to WinUI3 upgrade, but it fails at the following step. The two solutions I've tried are ones made via Windows Template Studio (pre 5.0)

Apply next step (Apply fix for [UA306_A1, UA306_A2, UA306_A3, UA306_A4, UA306_B, UA306_C, UA306_D, UA306_E, UA306_F, UA306_G, UA306_H, UA306_I]: Replace usage of Windows.UI.Core.CoreDispatcher, Replace usage of Window.Current.Dispatcher, Replace usage of App.Window.Dispatcher, Replace usage of Window.Dispatcher, Replace usage of Windows.Media.Capture.CameraCaptureUI, Replace usage of Micorsoft.UI.Xaml.Controls.InkCanvas, Replace usage of Microsoft.UI.Xaml.Controls.Maps.MapControl, Replace usage of Microsoft.UI.Xaml.Controls.MediaElement, Replace usage of Windows.Graphics.Printing.PrintManager, Replace usage of Windows.Security.Authentication.Web.WebAuthenticationBroker, Replace usage of Windows.UI.Xaml.Media.AcrylicBrush.BackgroundSource, Replace usage of Windows.UI.Shell.TaskbarManager)

@ujjwalchadha Could you take a look?

[ujjwalchadha]

Fixed by #1157 If this still persists, will reopen and take another look.

@ujjwalchadha, I just tried 0.3.331501 and it seems the Exception is now gone, but it still fails at this step:

Can you send the .clef file that is generated in the project?

[myokeeh]

@ujjwalchadha upgrade-assistant.clef.txt

[ujjwalchadha]

@myokeeh is it possible to send the repro code (The dispatcher queue related code in ViewLifetimeControl.cs) from the project that failed?

[myokeeh]

@ujjwalchadha this is the code that is generated by the tool as a result of the upgrade ViewLifetimeControl.cs.txt .

[ujjwalchadha]

Thanks! Tracking the new issue here: #1171 Closing this one as it seems to be a separate issue.

[ujjwalchadha]

1172 should fix the new issue
