Die Winui 3-App läuft mit F5 einwandfrei, kann jedoch nicht als einzelne .exe-Datei bereitgestellt werden ⇐ C#

[Anonymous]

Mit ChatGPT ist es mir gelungen, eine WinUI 3-Anwendung zu erstellen. Es ist überhaupt nicht viel: 2 Beschriftungen, 1 Eingabetext, 2 Schaltflächen und ein weiteres Textfeld, das Protokolle anzeigt. Hier ist ein Bild vom Laufen mit F5:


Wie Sie sehen können, funktioniert es. Jetzt möchte ich es packen, wieder mit KI-Tools, am Ende bin ich bei der Konfiguration angekommen:

Code: Select all

Paketierung über diese Befehlszeile

Code: Select all

dotnet publish -c Release -r win-x64 --self-contained true

und auch

Code: Select all

dotnet publish -c Release -r win-x64 --self-contained true /p:PublishSingleFile=true

und die resultierende exe-Datei ist etwa 120 MB groß, was aussieht, als ob darin die für die Ausführung erforderliche Laufzeit gebündelt wäre, ohne dass der Benutzer etwas installieren müsste (dies ist eine Voraussetzung). Das Problem ist, dass nichts passiert, wenn ich die exe-Datei öffne. überhaupt. Wie kann ich diese Anwendung verpacken, die wie vorgesehen mit F5 ausgeführt wird?
