Hope this helps You need to create your instance of BidirectionGraph using the type IEdge instead of TaggedEdge:

I think the issue was by ths following , A possible solution is to model your graph as an AdjacencyGraph> and construct a Dictionary, double> cost dictionary, where costs are your distances.
code :
// ...
private AdjacencyGraph<string, Edge<string>> _graph;
private Dictionary<Edge<string>, double> _costs;

public void SetUpEdgesAndCosts()
{
    _graph = new AdjacencyGraph<string, Edge<string>>();
    _costs = new Dictionary<Edge<string>, double>();

    AddEdgeWithCosts("A", "D", 4.0);
    // snip
    AddEdgeWithCosts("C", "B", 1.0);
}

private void AddEdgeWithCosts(string source, string target, double cost)
{
    var edge = new Edge<string>(source, target);
    _graph.AddVerticesAndEdge(edge);
    _costs.Add(edge, cost);
}
private void PrintShortestPath(string @from, string to)
{
    var edgeCost = AlgorithmExtensions.GetIndexer(_costs);
    var tryGetPath = _graph.ShortestPathsDijkstra(edgeCost, @from);

    IEnumerable<Edge<string>> path;
    if (tryGetPath(to, out path))
    {
        PrintPath(@from, to, path);
    }
    else
    {
        Console.WriteLine("No path found from {0} to {1}.");
    }
}
Path found from A to E: A > D > B > E
Getting connected components from a QuickGraph graph

will be helpful for those in need It turns out that you need to call the Compute method on the algorithm to actually get it to run!
I took your sample code and just added call to Compute:
code :
let x = QuickGraph.Algorithms.ConnectedComponents.
          ConnectedComponentsAlgorithm(undirGraph)
x.Compute()
x.Components 
|> Seq.groupBy (fun kv -> kv.Value)
|> Seq.map (fun (comp, vertices) -> 
    comp, vertices |> Seq.map (fun kv -> kv.Key))
[ (0, [{decimal = 1M;}]); 
  (1, [{decimal = 2M;}; {decimal = 18M;}]);
  (2, [{decimal = 3M;}]);
  (3, [{decimal = 4M;}; {decimal = 5M;}; {decimal = 24M;}; 
       {decimal = 6M;}; {decimal = 7M;}]);
  (4, [{decimal = 8M;}; {decimal = 9M;}; {decimal = 10M;}]) ]
Creating a undirected graph and traversing it using BFS in QuickGraph

like below fixes the issue Richard, QuickGraph does not do any of this for you, it only makes events available which you can subscribe to. By subscribing to those events you can respond accordingly. From the admittedly lacking QuickGraph documentation on Depth First Search (yes, I realize you're doing BFS and not DFS, but the concept of how to subscribe to events is the same):
InitializeVertex, invoked on each vertex before starting the computation, DiscoverVertex, invoked when a vertex is encountered for the first time, ExamineEdge, invoked on every out-edge of each vertex after it is discovered, TreeEdge, invoked on each edge as it becomes a member of the edges that form the search tree. FinishVertex, invoked on a vertex after all of its out edges have been added to the search tree and all of the adjacent vertices have been discovered (but before their out edges have been examined).

it helps some times You have to provide a FileDotEngine yourself; see for instance this example on Github. A simple FileDotEngine that generates a jpg could be:

will help you The Quickgraph-to-Graphviz-export can not write files, so you need to implement IDotEngine which handles the file writing.
