How to verify exception parameter value?

[stecydube]

I know I can use this:

act.Should().Throw<SomeException>().Where(ex => ex.MyList.Count > 3);

but I don't feel that's optimal.

Is there a better way to assert this condition and have a better message like when using Should on a variable?

Something like this?

act.Should().Throw<SomeException>().Which.MyList.Should().HaveCountGreaterThan(3);

So simple 😳
Thank you!
