You talked about trying this in both 2.6.1 and 2.6.2. Can you
distinguish between two things for me?

1) Which framework version you are referencing in the tests

2) Which NUnit version is being used to run the tests.

We attempt to guarantee backward compatibility (e.g.: NUnit 2.6.2
running 2.6.1 tests) but not forward compatibility (e.g.: NUnit 2.6.1
running 2.6.2 tests).

Title:
  Generic Test Fixtures fails with System.NullReferenceException

Status in NUnit V2 Test Framework:
  New

Bug description:
  Affects NUnit 2.6.1 and 2.6.2 when tests are run from Resharper or
  TeamCity. NUnit 2.6.0, 2.5.9 and possibly older works fine.

  This is the stack trace from TeamCity build log:

  Loading assembly is compiled for v4.0.30319, x86
  NUnit runner runtime is v4.0.30319, x86
  System.NullReferenceException: Object reference not set to an instance of an object.

  This is the test code that causes the failure:

  [TestFixture(typeof(ArrayList))]
  [TestFixture(typeof(List<int>))]
  public class IList_Tests<TList> where TList : IList, new()
  {
    private IList list;

    [SetUp]
    public void CreateList()
    {
      this.list = new TList();
    }

    [Test]
    public void CanAddToList()
    {
      list.Add(1); list.Add(2); list.Add(3);
      Assert.AreEqual(3, list.Count);
    }
  }
