In my xml i got this error

The Type or namespace name 'Sucesso' could not be found.

but i have this file in my project. I use Visual Studio for Mac and in this reference i have a symbol not identified. See image below

In the left botton i have something like a small icon. What happens this?
Below my xaml this page

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

            <Style TargetType="Button">
                <Setter Property="BorderRadius" Value="5" />
                <Setter Property="TextColor" Value="White" />
                <Setter Property="BackgroundColor" Value="#78319A" />
            <Style TargetType="Entry">
                <Setter Property="TextColor" Value="#757575" />
                <Setter Property="FontSize" Value="Small" />
            <Style TargetType="Label">
                <Setter Property="TextColor" Value="#757575" />
                <Setter Property="FontSize" Value="Small" />
                <Setter Property="HorizontalTextAlignment" Value="Center" />
        <StackLayout Orientation="Vertical" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" Padding="20">
            <StackLayout Orientation="Vertical" HorizontalOptions="CenterAndExpand" VerticalOptions="CenterAndExpand">
                <Image Source="ic_check.png" WidthRequest="100" HeightRequest="100" />
                <Label x:Name="successMessageTitle" FontSize="Large" FontAttributes="Bold" />
                <Label x:Name="successMessage" />
            <Button x:Name="btnBack" Text="Voltar" Clicked="btnBack_Clicked"/>

In the <Content... /> i get the error

My dev environment is: Visual Studio 2019 for Mac


This is the Code of Sucesso.amxl.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using Xamarin.Forms;
using Xamarin.Forms.Xaml;

namespace PerformaMobile.Page
    public partial class Sucesso : ContentPage
        public Sucesso(string title, string messageTitle, string message)
            this.Title = title;

            successMessageTitle.IsVisible = !string.IsNullOrWhiteSpace(messageTitle);
            successMessageTitle.Text = messageTitle != null ? messageTitle : string.Empty;

            successMessage.IsVisible = !string.IsNullOrWhiteSpace(message);
            successMessage.Text = message != null ? message : string.Empty;

        private void btnBack_Clicked(object sender, EventArgs e)

@igorkr_10 i posted the code above(Sucesso.axml.cs) and another page call this page this way.
await Navigation.PushAsync(new Sucesso("Ticket Cadastrado", messageTitle, message));

In this Line above i get this error message

The type or namespace name 'Sucesso' could not be found(Are you missing directive or an assembly reference?)

    In my resources file i put this Lines

    data name="Sucesso" xml:space="preserve"

    but does not work

    p.s. i removed <> because was render and only Sucesso appear

    If you use the whole name with the namespace as the prefix will it work? Call it like:

    await Navigation.PushAsync(new PerformaMobile.Page.Sucesso("Ticket Cadastrado", messageTitle, message));

    Moreover, try to double click the code which threw the error. Then click Quick Fix. It will offer some options to fix this issue.
