+## Beispiele für .NET 6 und .NET 7
+
+Die Beispiele für dieses Buch wurden ursprünglich für .NET 6 geschrieben. Kurz vor der Veröffentlichung des Buchs kam .NET 7 heraus. Da .NET 7 einige Verbesserungen für .NET MAUI gebracht hat, habe ich mich dazu entschieden, die Beispiele im main-branch auf .NET 7 zu aktualisieren. Um diese Beispiele ausführen zu können, benötigen Sie Visual Studio 2022, Update 17.4 oder höher.

+Im Branch net-6 finden Sie die ursprünglichen .NET 6 Beispiele. Zur Ausführung dieser Beispiele benötigen Sie Visual Studio 2022 Update 17.3 oder höher.
