WPF - adding a label around the edges in Graph #

Question

I could not work with WPF, so I used elementHost in Winform.

In my project (drawing a graph using graph #), I can draw vertices and edges, but I could not put labels around the edges.

The code:

string[] vertices = new string[] { "A", "B", "C" };
var g = new BidirectionalGraph<object, IEdge<object>>();

g.AddVertexRange(vertices);

g.AddEdge(new Edge<object>(vertices[0], vertices[1]));
g.AddEdge(new Edge<object>(vertices[1], vertices[2]));
g.AddEdge(new Edge<object>(vertices[0], vertices[2]));

graphLayout.Graph = g;

You can create a legend of color, not labels, and then color the edges.

if (FirstCase
{
    g.AddVertex("A");
    Color edgeColor = Colors.Green;

    g.AddVerticesAndEdge(new MyEdge("A", "B")
    {
        EdgeColor = edgeColor
    });
}
if (SecondCase
{
    g.AddVertex("B");
    Color edgeColor = Colors.Red;

    g.AddVerticesAndEdge(new MyEdge("B", "C")
    {
        EdgeColor = edgeColor
    });
}
