Same project on Mac, will build but won't launch, displaying same error.

[Lancelotbronner]

Same here except I'm on macOS Ventura (13.0)

Try installing the Xamarin.Android component from the VS4Mac installer. It shouldn’t be needed any more, but currently still is.

see https://github.com/dotnet/maui/issues/8894

The VS4Mac installer's Xamarin components are locked checked for me so they are already installed and it still doesn't work.

Hello Friends!, in my case, when I run my app from Terminal with dotnet build -t:Run -f net7.0-ios it work fine!!! but when I try using visual studio for Mac 17.4 I get this message: Can not execute MyMauiApp.cll the selected run mode is not supported for .net projects

I don't know the reason 😞

Same on 17.5.2 Stable and 17.6 Preview.

Same problem - Xamarin Android installed, VS for mac 17.5.5

The only solution for me was to clone the project again and in project properties -> general -> change the Output type for Executable again.

Seems more like a product issue, please report to the .NET MAUI repo for better visibility and we can get to help you! This samples repo does not have anyone actively monitoring it or any support. Hope this got resolved in the meanwhile!
