What do you mean with Bundle ID? I don't understand what you added exactly.

Can you elaborate a bit more on the exact steps that you have taken with the exact values that you put in somewhere? Also a reproduction is always super helpful.

Thanks!

Bundle ID is unique indentifier for each apps.
This problem just fixed by update dotnet workload and using VSCode for development.

But Visual Studio Mac cannot use again for long term production?

Ah ok! Glad you figured it out.

Yes, unfortunately official support for Visual Studio for Mac has stopped in August. So if it still works for what you are doing, thats great! But other things might stop working over time and will not be fixed any more.

The recommended way forward is using VS Code or use the remote build agent connected to Visual Studio on Windows.
