Title:
  Microsoft.Hpc.Scheduler test gets an exception

Status in NUnit Test Framework:
  New

Bug description:
  I have the following test:

  using Microsoft.Hpc.Scheduler;
  using NUnit.Framework;

  namespace TestHPC
  {
      [TestFixture]
      internal class TestHpc
      {
          [TestCase("HEAD-NODE-SERVER", 9)]
          public static void AllCoresPresent(string headNode, int expectedCores)
          {
              int totalCores = 0;

              using (IScheduler scheduler = new Scheduler())
              {
                  scheduler.Connect(headNode);
                  ISchedulerCollection nodes = scheduler.GetNodeList(null, null);
                  foreach (ISchedulerNode node in nodes)
                  {
                      totalCores += node.NumberOfCores;
                  }
              }

              Assert.AreEqual(expectedCores, totalCores);
          }
      }
  }

  I am using a Visual Studio 2010 solution that has the project with
  this test build against .NET 4.0. This is the only test in the
  solution.

  If I use NUnit 2.6.0 GUI or console runner, the test hangs in the
  middle.

  If I use ReSharper 7.1.1 Unit Test runner pointed at my local NUnit
  2.6.0 and run the test from the project compiled against 2.6.0
  nunit.framework.dll, the test passes quite quickly.

  If I switch ReSharper to run tests with built-in NUnit 2.6.2 and
  compile against 2.6.2, the test fails with this error:

  Microsoft.Hpc.Scheduler.Properties.SchedulerException : No connection could be made because the target machine actively refused it 127.0.0.1:6729
    ----> System.Net.Sockets.SocketException : No connection could be made because the target machine actively refused it

  If I use NUnit 2.6.2 GUI or console runner, the test hangs in the
  middle.

  There are no firewalls blocking port 6729 on the HPC server. All I did
  was switch the version of NUnit.

  There seems to be a difference in how ReSharper is launching NUnit
  from the way NUnit GUI and console runner work. If I did not have
  ReSharper, I would have no clue that my test could pass.

  ReSharper's behavior is observed in TeamCity when I run the test using
  NUnit runner. Looks like JetBrains have some consistency across their
  products that work better for execution of NUnit tests than native
  tools.

  I have a variety of other tests that work just fine after the switch,
  so the problem is constrained to Microsoft.Hpc.Scheduler tests (for
  now). I can provide more information if needed. Please help!
