Hi,

I have error

Views\RouteList.xaml(101,40): XamlC error XFC0045: Binding: Property "RouteStatusName" not found on "Models.Responses.GetRouteListResponseBase".

This error is after I add new properties to model and try binding this prop. My Model is in another assembly:

namespace Models.Responses
{
    public class GetRouteListResponseBase
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public DateTime PlannedDate { get; set; }
        public double Distance { get; set; }
        public RouteStatus RouteStatus { get; set; }
        public string RouteStatusName { get; set; }

        [JsonIgnore]
        public bool Today => PlannedDate == DateTime.Today;

        [JsonIgnore]
        public bool Late
        {
            get
            {
                return PlannedDate < DateTime.Today;
            }
        }

        [JsonIgnore]
        public bool Future
        {
            get
            {
                return PlannedDate > DateTime.Today;
            }
        }
    }
}

And here is my XAML. What I do wrong?

<?xml version="1.0" encoding="utf-8" ?>

    </StackLayout>
</ContentPage>

Error is with last Label (Text="{Binding RouteStatusName}").

    Is this the only error you are getting or are there others as well?
    Did you close and reopen the designer to see if the issue goes away?
    Are you sure that the UI project is referencing the project Models and not the assembly with the same name (check the project's references)?
