I'm following this tutorial to create my first Windows app. I'm at step 3, and if I try to run the applications I get a Windows.UI.Xaml.Markup.XamlParseException here
<TextBlock x:Uid="messageLabel" x:Name="messageLabel" Text=""></TextBlock>
Since I'm not even changing the names from the guide, what is going on?
EDIT 1: Complete error message
Eccezione first-chance di tipo 'Windows.UI.Xaml.Markup.XamlParseException' in App1.exe
