Customize rounded corner radius of a WPF polyline

Question

Hello, is it possible to set the corner radius of a WPF polyline to a custom value. For a WPF border it is possible. In my opinion, the polyline can only set StrokeLineJoin="Round", but not the radius:

<Polyline Points="0,0 0,100 200,100" StrokeLineJoin="Round" />

For border: CornerRadius="..." is possible:

<Border CornerRadius="8" ... />

Is there an easy workaround/hack to achieve custom corner roundings (at line joins) of polylines? (e.g. Microsoft Visio is able to do this.) Thanks!

Not that I know of but their is a hack... create your border or rectangle with corner radius set using expression blend and then convert to path? This will take a rectangle (with a corner radius set) and make it a path!
