[HandsomeGoldenKnight]

Usage Information

Material.Avalonia: v3.10.1; Avalonia: 11.2.7

Description

Material.Avalonia causes the CornerRadius of UserControl to fail to take effect.

Reproduction Steps

App.axaml:

<Application
	x:Class="MyAvaloniaApplication.App" 
	xmlns="https://github.com/avaloniaui"
	xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
	xmlns:idcr="using:Dock.Avalonia.Controls.Recycling" xmlns:ids="using:Dock.Settings"
	xmlns:material="clr-namespace:Material.Styles.Themes;assembly=Material.Styles" 
	xmlns:materialIcons="clr-namespace:Material.Icons.Avalonia;assembly=Material.Icons.Avalonia"
	RequestedThemeVariant="Default">
	<!--  "Default" ThemeVariant follows system theme variant. "Dark" or "Light" are other available options.  -->

	<Application.Styles>
		<FluentTheme />
		<material:MaterialTheme BaseTheme="Inherit" PrimaryColor="Purple" SecondaryColor="Lime" />
		<materialIcons:MaterialIconStyles />
	</Application.Styles>
</Application>

MainWindow.axaml:

<Window
	x:Class="MyAvaloniaApplication.Views.MainWindow"
	xmlns="https://github.com/avaloniaui"
	xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
	xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
	xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
	xmlns:views="clr-namespace:MyAvaloniaApplication.Views"
	xmlns:vm="using:MyAvaloniaApplication.ViewModels"
	Title="MyAvaloniaApplication"
	d:DesignHeight="450"
	d:DesignWidth="800"
	Icon="/Assets/avalonia-logo.ico"
	mc:Ignorable="d">
	<views:MainView BorderBrush="Black" BorderThickness="5" CornerRadius="20" />
</Window>

Expected Behavior

There are 4 rounded corners around UserControl, when I comment out <material:MaterialTheme BaseTheme="Inherit" PrimaryColor="Purple" SecondaryColor="Lime" /> in the app.axaml file

Actual Behavior

There are no rounded corners around UserControl, when I used MaterialTheme.

Regression?

No response

Known Workarounds

After I check the source code, I think CornerRadius="{TemplateBinding CornerRadius}" is missing in
ContentControl.axaml and UserControl.axaml.

P.S. I wonder if it's necessary to redefine UserControl and ContentControl

Anything else?

No response

Could you help with a pull-request?

P.S. I wonder if it's necessary to redefine UserControl and ContentControl

Yes, since Material.Avalonia can be used without any other theme.
