.NET Component for Floor Plan Designer application

Question

My next project is a kitchen designer application (CAD). Something like MS Visio or Home Suite app.

I am looking for a component that I can use as a design editor.

Front view is a must, view from the top and 3D are desired.

I want to be able to:

1. Drag'n'drop components on the floor plan.
2. Select and change size and color of the components.
3. Move components when dimensions of inner components change.

For now it is a desktop application (Windows Forms or WPF). But would be nice to have an option for silverlight open.

Question: any .NET components out there that do what I need (free or commercial)?
