System.ArgumentException: WorkflowManager: Model with id '5726da5a-70d5-458f-af67-611293d97912' is not available

I didn't check your whole files yet.
But the problem here is that you create Windows UI objects, for example Ellipse in method CreateParticle().
Remove those usings:

using System.Windows.Media.Media3D;
using System.Windows.Media.Effects;
using System.Windows.Shapes;

and, off course, all usages of classes which belong to them. They don't belong into a MediaPortal 2 model.
I guess you copied the code from the original Particles program.
You have to provide the code which calculates the particle positions and maybe some properties for the particles, but not the UI elements of the particles in your model. The UI elements come from the skin file.

Concerning the resourceWrapper and the contentPresnert:
I think I got the point now You use it that you have always a menu / the same menu, similar to PHP and templates where you have a main template and include the content templates^^ This would be the main usage of the resourceWrapper I guess. I will try this if I'm more advanced in the basics of MPF.
I somebody else wants to read smoe details about the contentPresenter:
What is a ContentPresenter? | .NET Zone

and a German one: wozu genau dient der ContentPresenter????

To make that work, in your "label", you need to write "{StaticResource BlackColor}" or "{ThemeResource BlackColor}".

Sorry, I forgotten the StaticResource/ThemeResource^^

Now to the timer problem:

Oh no, I would never change the skinEngine with my little knowledge of MPF right now^^
I'm playing with the helloWorld Plugin.. okay there is nothing as it was, but playing with MPF and doing some useless stuff gives you a feeling for MPF over the time

How can I block the windows message loop?!

it depends on this namespace:

using System.Windows.Threading;
...
DispatcherTimer timer = new DispatcherTimer();

I really don't know what's wrong because there is no much different to my test WPF application and there it worked fine. Maybe I have to subscribe to some MessageQueue?!
In the BaseTimerControlledModel.cs you subscribe to Messages, but you only detect the "SystemState.Running" and "SystemState.ShuttingDown"...

Here is my complete Model.cs, maybe you have a hint and thanks for your great help above
