How to define Marker-Start URI

[koglth]

Hi,
how can I define the marker-start uri to refer to a definition?

I want my svg look like this:

When I try to define the marker-start like this, I end up with an Uri format error:
path.MarkerEnd = new Uri("url(#arrow)");

Defining the arrow worked great but building the uri is my problem 🤦‍♂️

Any idea how to correctly format that?
Thank you for your help!

I found the solution in the Unit Tests: Tests/Svg.UnitTests/MarkerEndTest.cs
