Take the 2-minute tour ×  I know how to write this using Nunit,
Assert.That(exception,
Is.InstanceOfType(typeof(TypeNotRegisteredException)));  How can
I write the same thing using in Xunit, as Xunit does not have
Assert.That.  share|improve this question add comment  2 Answers

this answer Thanks Matt. It is what I was looking for. –

asking what is the equivalent of the InstanceOfType assert
rather than the equivalent of Assert.That. The latter is just a
better syntax that enables you to read your asserts like
English.  The equivalent of InstanceOfType assert in Xunit is
IsType:   Note that the nunit equivalent is, indeed:   (the
older IsInstanceOfType assert is deprecated -
