richtextbox - Extended WPF Toolkit - using the RichTextBoxFormatBar

Question

I've been trying to use the Extended WPF Toolkit so that I can make use of the RichTextBoxFormatBar but I seem to be going round in cirlces. Despite trying several examples on here and other sites I keep getting the same error messages:

The attachable property 'FormatBar' was not found in type 'RichTextBoxFormatBarManager'.

The type 'toolkit:RichTextBoxFormatBar' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.

I'm new to WPF so I'm know it's something I'm not picking up on rather than a bug, can anyone tell me what I'm doing wrong and save my sanity?

<UserControl x:Class="TestWPF_Richtextbox.UserControl1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:toolkit="http://schemas.xceed.com/wpf/xaml/toolkit" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300"> <Grid> <RichTextBox> <toolkit:RichTextBoxFormatBarManager.FormatBar> <toolkit:RichTextBoxFormatBar /> </toolkit:RichTextBoxFormatBarManager.FormatBar> </RichTextBox> </Grid> </UserControl>

EDIT: Both the library and the project are .Net 4. The version of the WPFToolkit.Extended.dll is V.1.6.0.0.

My own stupid fault.

I'd forgotten to unblock the DLL when I downloaded it as per the instructions which say that after downloading the ExtendedWPFToolkit_Binaries.zip you should then right click on it, select "Properties" and then "Unblock".

Hopefully this post will help someone else who has made the same mistake.
