The following check is not implemented because it is difficult to know exactly which fields should be marked with ``++NonSerialized++`` and I am afraid it will generate too many FPs:
* Non-serializable fields are not marked with the ``++System.NonSerializedAttribute++`` attribute.
We find mostly classes that derive from Exception in the projects we test and that's why they might not be a good source for checking issues and false positives (statistically).
