why telerik RadTimeLine dont show some properties

why telerik RadTimeLine dont show some properties

First, i have some difficulties to find, reference and use the control, i try referencing a lot of Telerik.Windows.Something and when i typed telerik:RadTimeLine the VS intellisense doesnt show anything. I ended up referencing ALL telerik dll, for now, the markup show me the RadTimeLine, but some properties are not found when i compile the projetc

Here is the test project (MyTestProject)

Thanks
