Hello Hein,

In R# you can configure a different runner from the R# built-in one:
ReSharper > Options > Unit Testing > NUnit, you can try it. I don't know if
anything like that is available for TeamCity as well, but nonetheless this
looks like a bug as runners should be backwards compatible. What happens if
you run the tests with NUnit's own runner, but a previous version?

Title:
  Generic Test Fixtures fails with System.NullReferenceException

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

  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);
    }
  }
