Abstract functionality of a window in WPF

[1DMF]

I seem unable to derive a window from my own abstract class that derives from window.

My code worked great when I was using Windows Forms, I was told I should start using WPF and now I can't get it to work?

ProgressForm - Abstract class

namespace HLP_Class_Library
{
    public abstract class ProgressForm : Window
    {
        public abstract void AddMessage(string msg);
        public abstract void ClearMessage();
    }
}

Progress_Info - Concrete window class derived from ProgressForm

namespace HLP_Class_Library
{
    /// <summary>
    /// Interaction logic for Progress_Info.xaml
    /// </summary>
    public partial class Progress_Info : ProgressForm
    {
        public Progress_Info()
        {
            InitializeComponent();
        }

        // add messages to form
        public override void AddMessage(string msg)
        {
            if (msg != null && msg != "")
            {
                this.Progress.AppendText(msg);
            }
        }

        // clear form messages
        public override void ClearMessage()
        {
            this.Progress.Document.Blocks.Clear();
        }
    }
}

Progress_Info XAML

<src:ProgressForm 
        x:Class="HLP_Class_Library.Progress_Info"
        xmlns="[URL unfurl="true"]http://schemas.microsoft.com/winfx/2006/xaml/presentation"[/URL]
        xmlns:x="[URL unfurl="true"]http://schemas.microsoft.com/winfx/2006/xaml"[/URL]
        xmlns:src="clr-namespace:HLP_Class_Library"
        Title="Progress_Info" Height="300" Width="300">
    <Grid>
        <RichTextBox x:Name="Progress" HorizontalAlignment="Left" Height="270" VerticalAlignment="Top" Width="292">
            <FlowDocument>
                <Paragraph>
                    <Run Text="RichTextBox"/>
                </Paragraph>
            </FlowDocument>
        </RichTextBox>

    </Grid>
</src:ProgressForm>

Error

The name "ProgressForm" does not exist in the namespace "clr-namespace:HLP_Class_Library".

Yes it does, intelisense even provided me the option?

What am I doing wrong? This was easy in WinForm, I'm clearly missing something obvious in WPF.

Thanks,

It's OK, what I have seems to be correct, it was another error causing an assembly to not compile and therefore couldn't see the class!

This WPF/XAML is going to take a little getting used to!
