WPF使用Fluent.Ribbon修改标题栏背景颜色

使用NuGet安装：Install-Package Fluent.Ribbon

修改App.xaml：

<Application.Resources>
    <!-- Attach default Theme -->
    <ResourceDictionary Source="pack://application:,,,/Fluent;Component/Themes/Generic.xaml" />
</Application.Resources>

前台代码：

<Fluent:RibbonWindow x:Class="WpfDemo.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:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:Fluent="urn:fluent-ribbon"
        xmlns:local="clr-namespace:WpfDemo"
        mc:Ignorable="d" Background="Bisque"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Button Click="Button_Click" />
    </Grid>
</Fluent:RibbonWindow>

后台代码：

using System.Windows;

namespace WpfDemo
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Fluent.RibbonWindow
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            var win = new MainWindow();
            win.Owner = this;
            win.ShowDialog();
        }
    }
}
