Xamarin Forms.Xaml.XamlParseException

Question

I am creating a xamarin behaviour to validate an email id, therefore I created the behaviour file and tried to localise it in XAML file but I get the below error

Answer 1

I feel your XAML is clean. Looks error free. I think the problem is with the EmailBhvrclass in Validation. I suggest you to verify it. Make sure that the assembly name in XAML is also correct. XamlParseException can also occur with the incorrect assembly name..
