    Hi Nathan, Thanks for posting this code.  I  have been playing with the MSF and it is nice to see many pieces in action here.  In an earlier posting, you have mentioned that you could use either "rank" or "assign" to display the results, but you chose to use "assign" to demonstrate some more LINQ capabilities.  However I am not getting the expected results with using "assign" alone.  Do we need to sort it somehow?  Thanks! Tekin.

    Hi Tekin, Can you elaborate? In the last part of this sample I am doing a "select" from assign to print out the tour.  Assign[i, j] == 1 means that the arc i -> j is in the tour.

    Hi Nathan, Select statement returns j's for active arcs.  When you print them out with "->" I assumed that the order represented the route taken.  It is not the case however.  You can confirm that by printing the full report and construct the route from it.  Thanks.

    Hi Maria, you need to download and install the Express version of Solver Foundation from code.msdn.microsoft.com/solverfoundation.  Make sure your project is .Net 4, NOT .Net 4 Client Profile. Otherwise you will not see Solver Foundation listed as a .Net reference.
