Add shapes like Arc and RegularPolygon from Microsoft.Expression.Drawing

[wldevries]

The Microsoft.Expression.Drawing library had some really great reusable shapes. Unfortunately it is no longer maintained by Microsoft and the library is .NET 4 only. It would be great to bring some of these shapes to WPF on .NET 5 and UWP / WinUI.

Did @microsoft release reference source for these libraries or is it closed source only? I couldn't find it anywhere else!

[wldevries]

As far as I know Microsoft has only released the xaml behaviors part of the Blend SDK as open source.

@wldevries Thanks for the request. Will open this up for further discussion and see what community members think about this feature.

So, ArcSegment for paths still work in UWP, as discussed in this article. That sample works in UWP as-is for me.

@XamlBrewer also had a sample on how to do arcs in composition as well, though that's a bit more complex.

There's also the Polygon uwp shape that can be used directly.

@wldevries do you have links to the old API docs or example usage and screenshots? Trying to understand how the existing API set can't handle these types of scenarios. Could you elaborate a bit more on what you'd like to see here?

For now, moving this to a discussion as this is a broad idea/topic.

The shapes I'm referring to are port of the Expression Blend SDK for WPF. In addition to Arc and RegularPolygon there was also a BlockArrow. All these elements derive from FrameworkElement and can be used in normal layout without having to resort to Paths. The ArcSegment mentioned by @michael-hawker has similar functionality to Arc, but is harder to use for novice developers as it needs to be embedded in a Path control.
