No background and invisible controls when theme is set to dark

[dawemeister]

I tried to create a basic project using the getting started tutorial.

Here is my App.xaml

And here is my MainWindow:

And the result is this:

I also tried other controls, but nothing rendered at all.
Nuget package is installed, and no errors shown.
What did I do wrong?

OS: Windows 11
Framework: .NET 6

You have not changed the MainWindow background but you have selected the Dark theme in App.xaml.
Most likely, you have a white background and a white icon, thus nothing is visible.

For example, you can do it this way:

<Window
    ...
    xmlns:ui="http://schemas.lepo.co/wpfui/2022/xaml"
    Background="{ui:ThemeResource ApplicationBackgroundBrush}">
</Window>

This was my problem also, according to the get started, you "only"(?) need to add the app.xaml stuff, iirc there is nothing that says you need to add "Background="{ui:ThemeResource ApplicationBackgroundBrush}"" to the window.
