I write here, because I launched my project this morning and suddenly, I realized XAML didn't work any more whereas it worked very well before. Without making any modifications.
So this morning I had, a red background with "MockView" on it. I updated VS 2019 Preview tool. The message "Mockview" disappears. However, when I want to preview a Tabbed page (not the others) here is the result.
If you have any ideas or solutions, I appreciate ... Cause I didn't really understand what happened.
So my second prob is : when i want to run my app onto the emulator (Android 9.0 AP28) with Debug or Release mode, the following msg is display in output:
Unable to resolve conflict between "mscorlib, Version=188.8.131.52, Culture=neutral, PublicKeyToken=b77a5c561934e089" et "mscorlib, Version=184.108.40.206, Culture=neutral, PublicKeyToken=7cec85d7bea7798e". Choix arbitraire de "mscorlib, Version=220.127.116.11, Culture=neutral, PublicKeyToken=b77a5c561934e089".
And I know what it's really ...
Thank's a lot if you any ideas, I'll take it.
