Tests that use a transactionscope fail to run

Hello all,

I don't seem to be able to run my integration tests.
They are nunit tests that use a transaction scope to revert the database to a known state, and all fail with the error below at [2]. Each test has a setup and teardown like [1] and the error occurs when creating the TransactionScope.

Has anyone seen anything similar? The tests run on the console runner and on the resharper runner.

Thanks,
Bruno

        [SetUp]
        public void Setup()
        {
            _TransactionScope = new TransactionScope(TransactionScopeOption.RequiresNew);
        }

        [TearDown]
        public void TearDown()
        {
            if(_TransactionScope != null)
                _TransactionScope.Dispose();
        }

Okay, it was an error in my machine.config that apparently didn't surface on the rest of the test runners.

I've fixed it and ncrunch runs ok :)
