I upgraded from 18.2 to 18.3 today (VS2015). I have a lot of code with properties and classes that start with the word Producer. They're all flagged with the warning that they don't match rule 'Properties' or 'Types and namespaces' and that the proper name is just without the word "Producer".
e.g. ProducerName → Name 'ProducerName' does not match rule 'Properties'. Suggested name is 'Name'.
When I select the change rule options to see what's causing it I only see the one rule UpperCamelCase which all of my properties and classes match. Nothing else is getting flagged like this, just things that start with the word Producer.
