WhatDoIHave() throws IndexOutOfRangeException in v6.0.0

[hellfirehd]

In dev I always log WhatDidIScan() and WhatDoIHave() on startup. After upgrading to v6.0.0 it started throwing the following:

System.IndexOutOfRangeException: Index was outside the bounds of the array.

I can do a Live Share session if it would help.

I had this exact same issue in a previous version after adding

services.AddHttpClient();

to my Startup.cs config, but in version 6 I now get this instead:

System.NullReferenceException: 'Object reference not set to an instance of an object.'

Good times. I'm on it.

[jeremydmiller]

I'm hardening the code to trap exceptions and just use Type.Name if it can't figure it out, but I can't reproduce this locally guy. @jdub4237's problem is unrelated.

[jeremydmiller]

for @jdub4237 I added better exceptions, but I have no idea what that's from, and again, I'm not able to reproduce the issue locally.
