Unhandled exception" error when debugging Visual Studio Community 2019

Question

Hello everyone,
I'm facing a problem on Visual Studio Community software on Windows 11 with required specifications. When I create a WinUI 3 project (Desktop application in C#) and I debug the application without even inserting any code, the software loads symbols from the Microsoft symbol server until it stops on an error.
I will detail all the steps in pictures:

1. I create a project in the V.S editor
2. I choose the type of project corresponding to the one indicated in the Microsoft WinUI3 documentation: https://learn.microsoft.com/en-us/windows/apps/winui/winui3/create-your-first-winui3-app
3. I name my project
4. I choose the template with the Windows Template Studio (SDK)
5. The window opens and the project is created
6. I run the x64 debugging of "TestApp".
7. The output window appears and registers the events
8. The error window opens
9. I redo the same steps debugging x64 "TestApp (Package)
10. The output window opens
11. Another error also of the type exception not generated opens
    ............ And I'm stuck
    I hope I have provided enough details so that you can help me.
    Thanks in advance

Answer 1

Did you install the Windows App SDK Runtime ?
Microsoft.WindowsAppRuntime.Redist.1.0.0.zip from Downloads for the Windows App SDK

Answer 2

I realize that I have to my great surprise not installed this sdk. I now have other app creation options that correspond to the ones described in the Microsoft documentation. My application is now working ! Thanks a lot for your help !

Hello again,
I am forced to ask for your help again. I am facing the same problem when I use a function. I use the TabView module which works well in this configuration:

but displays an error when debugging by adding those functions:

Thanks in advance
