As per my recent post, I have created a custom rule that enforces a "_" prefix on all private fields. I have found several fields that are incorrectly failing this rule, for example:
private ITestObject _o1;
The action I am prompted with says: Rename to '__o1'
The rule that I have created is as follows:
UseOrAvoidCertainPrefixes
NextCharCaptalizationStyle: Lower
PrefixToCheck: _
PrefixUsage: Use
