The default appearance of the NavigationView in WinUI3 Gallery or an app created with a template studio has a space at the top. However, it looks different in apps created with Visual Studio default templates.I don't think it's controlled by the ViewModel or anything else. Why does it look different?

Even if you modify the ShellPage of an app created with a Template Studio as follows, there is still a difference in appearance.
public sealed partial class ShellPage : Page
{
public ShellPage()
{
InitializeComponent();
}
}
<Page
x:Class="TemplateStudioApp.Views.ShellPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006">

</Page>
That space at the top is actually the AppTitleBar. This code should create the same look.

In Template Studio, these resources from Styles/Thickness.xaml were the solution.
I'm trying to make a navigation view with MUXC in my app but is donesn't work:

Target: Universal Windows version 2004
Min. Target: Universal Windows version 1809
Does anyone knows how to solve this? Is this a problem in my code or in the platform?
Normally this is not required but have you tried to encapsulate your frame in the Content property of your NavigationView ?
<muxc:NavigationView.Content>
<Frame x:Name="contentFrame9" />
</muxc:NavigationView.Content>
With the Target and MinTarget SDK, my app successfully display your page :
I have referenced the last version of Microsoft.UI.Xaml library :
Add following xaml code into App.xaml will solve your problem.

<XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls"/>

I'm new to XAML and WPF, and I think it's something small that I don't get. anyway this is the start of the XAML code:
<Window x:Class="SchoolApp.MainWindow"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:vm="clr-namespace:School.ViewModel"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<x:Array x:Key="ColorListString" Type="local:ComboBoxItemString"/>
<local:ComboBoxItemString ValueString = "Red" />
<local:ComboBoxItemString ValueString = "Green"/>
<local:ComboBoxItemString ValueString = "Blue"/>
</x:array>
</Window.Resources>
<Grid Background="#FF99993A"....
and the error is:
the closing tag "Window.Resourses" is mismatched
Thanks for anyone who can help :)
Change the line
<x:Array x:Key="ColorListString" Type="local:ComboBoxItemString"/>
to
<x:Array x:Key="ColorListString" Type="local:ComboBoxItemString">
otherwise the array's content and its closing tag will not match...
I have some vector icons I want to use throughout my windows universal application. I've added them to a resource dictionary, added the dictionary to a merged dictionary in app.xml, and tried using the resources in a page. The images actually show up in the editor preview window, but throw an error when I attempt to debug the application.

Error throw when debugging:
A first chance exception of type 'Windows.UI.Xaml.Markup.XamlParseException' occurred in MagicStats.Windows.exe
WinRT information: Failed to assign to property 'Windows.UI.Xaml.Controls.ContentControl.Content'. [Line: 79 Position: 25]
The error message seems to indicate that the binding failed, but it actually works in the design window. Any thoughts are appreciated.
i would like to create a custom base class for some of my UserControls.
Doing this in VS2008 is fine and compiles as expected, but when i edit the control in Blend 3 the base class in the blabla.g.vb is always changed back to System.Windows.Controls.UserControl.
How can i force Blend to keep the assigned base class?

Christoph
Can you show your XAML?
I suspect the case is your XAML is like this:
<UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:SilverlightApplication15"
x:Class="SilverlightApplication15.MainPage"
Width="640"
Height="480">
<Grid x:Name="LayoutRoot"
Background="#FF313131" />
</UserControl>
When it should be something like:
<local:BlahBlah xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:SilverlightApplication15"
x:Class="SilverlightApplication15.MainPage"
Width="640"
Height="480">
<Grid x:Name="LayoutRoot"
Background="#FF313131" />
</local:BlahBlah>
The .g.vb file is generated from the XAML so it's not a file you should edit directly.
