Assert.Throws() hides details of inner AssertionException

[Sergey S.]

NUnit 2.5.9.10348

If AssertionException happens in a delegate provided to Assert.Throws() the diagnostic message does display no details making it hard to know which of asserts failed:

Test 'Test.Issue' failed:
  Expected: <System.InvalidOperationException>
  But was: <NUnit.Framework.AssertionException>

instead it would be good to display the assert message if AssertionException was thrown like:

Test 'Test.Issue' failed:
  Expected: <System.InvalidOperationException>
  But was: <NUnit.Framework.AssertionException> ("Cannot start with zero")

plus the inner stack trace. Please see the test attached.

Normally, one would expect Assert.Throws to be used with one of the methods under test rather than with a test method. Nevertheless, it seems useful to give more info about the exception that was actually thrown.
