+1 for adding a simple svg2xaml console application (to be used from build scripts!).
I wrote my own, which is as simple as:
var wpfDrawingSettings = new WpfDrawingSettings();
wpfDrawingSettings.IncludeRuntime = false;
var fileSvgConverter = new FileSvgConverter(true, false, wpfDrawingSettings);
if (!fileSvgConverter.Convert(Path.GetFullPath(args), Path.GetFullPath(args)))
...could need some options and error handling.
And with some Nokogiri-magic I use this in my rake build script to convert all SVG-Icons/Images to DrawingImages in resource dictionaries.
So far, this works pretty well and besides the locale issues, the SVG's are converted to XAML without any problems.
Everything else I tried before to convert SVG to XAML didn't work very well.
You deserve a BIG THANK YOU! for SharpVectors!
