Hi,

I am trying to learn how to make a WPF application. I am having a few issues one of them being the error message "Partil declaration of WPF_Test.MainWindow must not specify different base classes".

The code below is an example of a very quick WPF application that gives this error message. My application has more code in but even this simple application is being a pain! Please see the code below.

Any help would be great!

<RibbonWindow x:Class="WPF_Test.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        
    </Grid>
</RibbonWindow>

if u see ur xaml it inherits from RibbonWindow , while ur code behind is from Window, change that to RibbonWindow

public partial class MainWindow : RibbonWindow
    {
        public MainWindow()
        {
            InitializeComponent();
        }
    }
