'WPF Change Visibility during design-time

My CustomControls UI element Visibility is bound through a BoolToVisibilityConverter, see code below :

<cc:CustomFFU LabelText="FFUZoneF_2-1"  HorizontalAlignment="Center" VerticalAlignment="Center" Grid.Row="2" Grid.Column="1" Width="55" Height="35" 
        InstanceAddress="MCS1.Cleanroom.ProcessCell.UN_ZonesF.EM_FFU.CM_FFU2_1" 
        Visibility="{Binding VisibilityFFUView, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource BoolToVisibilityConverter}}" />

The code works as it should, however during design-time the visibility is Collapsed. So every CustomControl on my window is not visible during development. Quite annyoning..

How is the visibility during design-time fixed to Visibility? Ps. when I delete the BoolToVisibilityConverter, the status changes from Collapsed to Visible? Perhaps, because when designing the value represent false. Just a guess.

If you are using Visual Studio, you should add d:Visibility="Visible" property in xaml element that you want to be visible in design time

like this:

<Button Visibility="{Binding Property}" d:Visibility="Visible" />

and make sure that you have Ignorable="d" from "http://schemas.openxmlformats.org/markup-compatibility/2006" namespace on your root xaml element like this:

<Window x:Class="WpfApp2.MainWindow"
                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
                xmlns:local="clr-namespace:WpfApp2"
add this --->   xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
and this --->   mc:Ignorable="d"
                Title="MainWindow" Height="450" Width="800">
    <Grid>
    </Grid>
</Window>

This doesn't work in Rider wpf designer
