.NET6 Win UI Microsoft.DesktopBridge.props not found when using dotnet cli

Question

I am creating a .NET6 WinUI application which works and runs fine when built and executed via Visual Studio 2022.

If I try to build via the cli (dotnet build) I get an error that Microsoft.DesktopBridge.props is not found.

error MSB4019: Das importierte Projekt "C:\Program Files\dotnet\sdk\6.0.100\Microsoft\DesktopBridge\Microsoft.DesktopBridge.props" wurde nicht gefunden. Stellen Sie sicher, dass der Ausdruck in der Import-Deklaration "C:\Program Files\dotnet\sdk\6.0.100\\Microsoft\DesktopBridge\\Microsoft.DesktopBridge.props" richtig ist und dass die Datei auf dem Datenträger vorhanden ist.

The file doesn't exist at that location but at C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Microsoft\DesktopBridge, in the install directory of my VS 2022 installation.

If I fix the path in my wapproj file, the build error disappears (but the build fails with other errors).

I don't understand why it's working out of Visual Studio but not via the cli. Do I need to provide additional arguments? Is there a way to see the commands that Visual Studio executes when building/packaging? I appreciate any help or links to documentation about this that I might have missed.

I also tried to create a blank project, error is the same.

My tool setup:

• VS 17.0.1 (2022)
• NET 6.0.100
• Project Reunion VS Extension 0.8.4
• all versions are stable, no previews

My wapproj file:
