I’m a frequent user of the [ExpectedExceptionAttribute] but found out lately that its use is not recommended (anymore).
While the class itself is not deprecated, there are good reasons to use the Assert.ThrowsException() or Assert.ThrowsExceptionAsync() when writing unit tests.
It should not be too hard (as in: it is easy) to implement this. Are you aware of other test frameworks that als support this obsolete/anti-pattern approach?
