WPF UserControls Sample in VB.NET

Had to start writing WPF UserControls because there is no ImageButton and no NumericUpDown in the WPF toolbox. Made many searches, snippet conversion from C# and read the documentation. Maybe it's useful for interested persons to have an example in VB that shows a bit more than just the minimum requirements.
Most parts are based on code and most of of the xaml was created by the designer.
The solution is a 'WPF User Control Library (.NET Framework)' which can hold several controls side by side. Xaml and code can easyly be found for fixing and improving. New controls or variations can be added at any time.
I've added a WPF application to the solution to test the controls in place.

Other WPF applications can use the controls by adding a reference to the library and adding the namespace to the window. This can be done by typing 'xmlns:ucs=' and selecting the corresponding item from the list (WpfUserControlsSampleVb). Then the controls can be inserted to the panel by typing, for example, <ucs:ImageButton/>
-'ucs' is a short reference name defined by the user, must be unique-

Adjustments to the control can be made with the designer and in the Properties window, quite comfortable:

It should be possible to modify existing controls.
It should also be possible to combine a number of controls to one new control.

The controls:

ImageButton My first simple ImageButton. Some parts were created with Blend. I've tested it a while and it seems to work

ImageButton2 Improved ImageButton, can place the image left and right, added padding, margin, and TextAlignment. Not much tested

NumericUpDown Tried to make it almost as comfortable as the WinForms control is

ProgressCircle (ProgressPie) – Visualisation of progress. A bit geometry and a bit rendering

Knob Like a volume knob on a classic radio. A mixture of ProgressCircle and NumericUpDown.
