Adding Reference to WPF Toolkit
Extended Assembly
This blog is referenced in several of my articles.
To use a control that is defined in the WPF Toolkit Extended, you must add reference to
the WPFToolkit.Extended.dll assembly. You can download Extended WPF Tookit from
the CodePlex or you can use the WPFToolkit.Extended.dll available with this
download. All you need is the DLL.
After downloading the
WPFToolkit.Extended.dll, you can add reference to your project by right
clicking on the project name in Visual Studio, select Add Reference and browse
the DLL.
See Figure 1.

Once the assembly
reference is added, the next step is to import the namespace in XAML using the
xmlns. As soon as you type xmlns in XAML you should see the http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit/extended
option in the list. See Figure 2. If you do not see this URL, please read the
next section.

Unblocking the WPF Toolkit Assembly
If an assembly reference
is not added to your project correctly, you will see the following message when
you build your application.
Unable to load the metadata for assembly 'WPFToolkit.Extended'
You get this message
when try to add reference to the Extended WPF Toolkit to a project and build
the project. The problem here is when
you download an assembly from a Website, it is block by default. All you need
to do is, unblock the assembly.
Right click on the DLL
and click Unblock button.
See Figure 3.

Remove and add reference
again in your project to reflect the changes.
