Just tried it, error still persists.

Did you try to clone repo again? What is a version of VS?

[Samuel12321]

yes, re-cloned repo
Vs Version 16.11.1

[michalleptuch]

I think it's problem with your VS. I use v16.9.8

[michalleptuch]

I checked it and other my Desktop Bridge apps again. It's an issue in Visual Studio >= 16.10.0. Even Visual Studio 2022 Preview can't build my projects. For example, Ink Workspace has the same issue:

Validation error. error 80080204: App manifest validation error: Line 66, Column 27, Reason: The field "*[local-name()='Extensions']/*[local-name()='Extension']/*[local-name()='InProcessServer']/*[local-name()='ActivatableClass']" with value "Microsoft.Toolkit.Win32.UI.XamlHost.XamlApplication" must only be declared once. A duplicate exists on Line 60, Column 27. InkWorkspace.Package D:\Repozytoria\InkWorkspace\InkWorkspace.Package\bin\x64\Debug\AppxManifest.xml

I think someone smarter should take a look at this problem @marb2000.

[Samuel12321]

did you find a way around this?

No update at this moment 😔

plus there is a MSB3270 warning:

Severity Code Description Project Path File Line Suppression State
Warning MSB3270 There was a mismatch between the processor architecture of the project being built "x86" and the processor architecture of the reference "C:\Users\samue\Source\Repos\rounded-flyout\RoundedFlyout.Controls\bin\x64\Debug\RoundedFlyout.Controls.dll", "AMD64". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project.
