Hello, I'm new to Quickgraph and I've been working on an implementation of Breadth-First Search, I need to calculate the distance between an arbitrary start/root node and an end node. I have the following instantiation of a distance recorder:
var distObserver = new UndirectedVertexDistanceRecorderObserver<Vertex, TaggedEdge<Vertex, double>>();
where Vertex is a class I defined elsewhere in code.
For some reason I keep getting the error:
'QuickGraph.Algorithms.Observers.UndirectedVertexDistanceRecorderObserver<_469_A3.Vertex,QuickGraph.TaggedEdge<_469_A3.Vertex,double>>' does not contain a constructor that takes '0' arguments
Looking online, I've found other examples seem to declare it just as I have above without any complaint, I'm not sure what I'm doing wrong. Also, I've read that the AlgorithmsExtension handles this manually, is there an example of this somewhere on
this site?? Thank you.
