Fluent.Ribbon is an open-source WPF Ribbon control library that implements Microsoft's Fluent UI design guidelines. It provides a rich set of controls and styles to create modern, Office-like user interfaces for Windows desktop applications.

Pros

• Implements Microsoft's Fluent UI design, providing a familiar and professional look
• Extensive set of customizable ribbon controls and components
• Active development and community support
• Compatible with .NET Framework and .NET Core/5+

Cons

• Steeper learning curve compared to standard WPF controls
• May require more resources than simpler UI frameworks
• Limited to Windows desktop applications (WPF)

Code Examples

1. Creating a basic Ribbon window:

<Fluent:RibbonWindow x:Class="MyApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:Fluent="urn:fluent-ribbon"
        Title="My Ribbon App" Height="450" Width="800">
    <Fluent:Ribbon>
        <!-- Ribbon content goes here -->
    </Fluent:Ribbon>
</Fluent:RibbonWindow>

2. Adding a Ribbon Tab with a Group and Button:

<Fluent:Ribbon>
    <Fluent:RibbonTabItem Header="Home">
        <Fluent:RibbonGroupBox Header="Actions">
            <Fluent:Button Header="Click Me"
                           LargeIcon="/Images/myicon.png"
                           Click="Button_Click"/>
        </Fluent:RibbonGroupBox>
    </Fluent:RibbonTabItem>
</Fluent:Ribbon>

3. Implementing a Quick Access Toolbar:

<Fluent:Ribbon>
    <Fluent:Ribbon.QuickAccessItems>
        <Fluent:QuickAccessMenuItem Target="{Binding ElementName=SaveButton}"/>
        <Fluent:QuickAccessMenuItem Target="{Binding ElementName=UndoButton}"/>
    </Fluent:Ribbon.QuickAccessItems>
    <!-- Ribbon content -->
</Fluent:Ribbon>

Getting Started

1. Install the Fluent.Ribbon NuGet package:

   Install-Package Fluent.Ribbon
   

2. Add the Fluent.Ribbon namespace to your XAML:

   xmlns:Fluent="urn:fluent-ribbon"
   

3. Replace your main window with a RibbonWindow:

   <Fluent:RibbonWindow ...>
       <Fluent:Ribbon>
           <!-- Add your ribbon content here -->
       </Fluent:Ribbon>
   </Fluent:RibbonWindow>
   

4. Start adding Ribbon components like tabs, groups, and buttons to create your UI.
