Window.SetTitleBar method is missed in WinUI/Uwp

[BorzillaR]

Can`t find a Window.Current.SetTitleBar method on migrating my project from Uwp to WinUI/Uwp. Was it renamed?

It is not present at the moment, part of the limitations of the preview.

I need this as well. I'm working on a port of our UWP application to WinUI and ran into this issue.

I need this to port my UWP app to a WinUI 3 desktop application (the port is necessary to take advantage of NET 5).

Window.SetTitleBar is now available in Preview 4, along with neighboring Window.ExtendsContentIntoTitleBar: API doc

Just a quick clarification needed regarding .setTitleBar() usage.

MainWindow.xaml

<Window
    
    x:Class="Wrath.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Wrath"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">
    
    <Grid>
        <!-- ... -->
        <TextBlock x:Name="CustomTitleBar">Custom title text</TextBlock>

        <!-- ... -->


    </Grid>
</Window>

MainWindow.xaml.cpp

MainWindow::ExtendsContentIntoTitleBar(true);
MainWindow::SetTitleBar(?);

Do I have to make CustomTitleBar a UIElement, if so, how?

Or am I missing something here?

This is based on the example (only for .cs) provided from:
