== How to fix it in NUnit

Remove the `ExpectedException` attribute in favor of using the https://docs.nunit.org/articles/nunit/writing-tests/assertions/classic-assertions/Assert.Throws.html[Assert.Throws] assertion.

=== Code examples

==== Noncompliant code example

[source,vbnet,diff-id=2,diff-type=noncompliant]
----
<Test>
<ExpectedException(GetType(ArgumentNullException))>  ' Noncompliant
Public Sub Method_NullParam()
    Dim sut As New MyService()
    sut.Method(Nothing)
End Sub
----

==== Compliant solution

[source,vbnet,diff-id=2,diff-type=compliant]
----
<Test>
Public Sub Method_NullParam()
    Dim sut As New MyService()
    Assert.Throws(Of ArgumentNullException)(Sub() sut.Method(Nothing))
End Sub
