Want to map an Property from an Model to an ViewModel. But these Propertys of different types.

Model = Int
ViewModel = Enum

So is it possible to cast in the mapping?

No, Casting is not supported.

Ok. So what I have to do?

Implement 2 Propertys in the ViewModel. One with the same type like in the model. And one with the new type. But then its difficult to map the both propertys.

You can override both the OnModelPropertyChanged and OnPropertyChanged in the view model. Then you know which model has changed which property and do the cast yourself.

Now I did it in this way. And it works.
public Unit Unit
    get { return GetValue<Unit>(UnitProperty); }
     private set { SetValue(UnitProperty, value); }
public OpMode OmUnit
    get { return (OpMode)Unit.OmUnit; }
        if ((OpMode) Unit.OmUnit != value)
            Unit.OmUnit = (int)value;

That's a good option as well.
