Why await operator doesn't work in NUnit TearDown?

I have API integration tests in nUnit. When I added execute async method in [TearDown] I saw that await operator doesn't work ...

[TearDown]
public async void TearDownAsync()
{
  var response = await service.GetTasksAsync();

  if (response.Count > 0)
  {

  }
}

In this sample method GetTasksAsync() is executed but doesn't wait for result. When I change it to use Wait() it's ok.

[TearDown]
public void TearDown()
{
  var response = service.GetTasksAsync();
  service.Wait();

  if (response.Result.Count > 0)
  {

  }
}

I think the problem is in the[TearDown]. Method is executed but thread is ended prematurely. In [Test] method everything is ok. Is it a bug in [TearDown] or I'm using it improperly?

Define your method as `async Task`, not `async void`. – Jeroen Vannevel Aug 29 '14 at 06:54
what for you call GetTasksAsync? – Sowiarz Aug 29 '14 at 06:59
@JeroenVannevel Doesn't work. "ignored invalid signature for setup or teardown method setup" – Mariusz Aug 29 '14 at 07:19

@Mariusz: async teardowns and setups are not supported in Nunit: https://github.com/nunit/nunit-framework/issues/60. I suggest making the calls blocking or switching to MStest. – Jeroen Vannevel Aug 29 '14 at 07:23
