It seems that tizen.net doesnt support typical .net text syntaxt.

So while one might not expect “\n” to insert a carrige return, they would expect

System.Environment.NewLine

to work, but it doesnt either.

Fortunatly there is some information in another non .net related tizen thread:

https://developer.tizen.org/forums/native-application-development/answered-popup-how-show-line-breaks?langswitch=en

I would expect the transition over to standard .net text handling.

Perhaps ill file a bug someday
