Is this a regression from previous behavior?

Yes, this used to work in .NET MAUI

Last version that worked well

Did you find any workaround?

Well, deleting the AppResources.pt fixes it, though loosing translations :)

@bcaceiro If you try this in a .NET Android application that doesn't implement the MAUI UI framework (dotnet new android), does it also crash? This seems like it will be a runtime issue and not a MAUI UI one.

[bcaceiro]

@drasticactions no idea, tbf not quite familiar with AppResources in a dotnet android app

[dellis1972]

I tried to repo and Preview 6 of .net 9 and I am unable to do so. I tested both pt and es languages on an emulator.

[bcaceiro]

@dellis1972 - It is on preview7 - the template doesn't have that option available.

I have a reproduction link in the issue. Tested on a real device though

[dellis1972]

So I can't repo on device or emulator using preview 7. @grendello can you take a look when you get a moment?

[bcaceiro]

Changed the description of the reproduction steps - It only happens in RELEASE mode

[tranb3r]

Any update?

[dellis1972]

@grendello when you get a moment can you take a look at this one?

[grendello]

@dellis1972 There's a chance c978f35 already fixed it, I'll try to take a look this week.

[tranb3r]

This is still happening in net9-rc1.
