Don't use hard-coded "null", use Microsoft.IdentityModel.Tokens.Utility.Null instead.

Why renaming this class? The original ConfigurationValidationException is thrown when a configuration fails to validate, which seems right to me.

Assert

Let's add a check here, if the theoryData.PresetCurrentConfiguration is set to true, throw since this should never be the case.

[brentschmaltz]

We are throwing a new exception that does not derive from a previously thrown exception, we need to derive InvalidConfigurationException from the exception that was previously thrown.

Please either unify jitter or cut a PBI to unify jitter before checking in. We shouldn't proliferate different ways of doing this in our code without a plan to address.

Approving with the expectation you'll open an issue before merging. (same goes for pending error message marking as PII but that's probably easier to just fix).
