The following default StyleCop rules have been disabled for the add-in and unit-test projects.
SA1101: PrefixLocalCallsWithThis
SA1126: PrefixCallsCorrectly
SA1310: FieldNamesMustNotContainUnderscore
SA1633: FileMustHaveHeader
SA1634: FileHeaderMustShowCopyright
SA1635: FileHdeaderMustHaveCopyrightText
SA1637: FileHeaderMustContainFileName
SA1640: FileHeaderMustHaveValidCompanyText
SA1642: ConstructorSummaryDocumentationMustBeginWithStandardText
SA1643: DestructorSummaryDocumantionMustBeginWithStandardText

Namely, this disables the requirement for file headers, links within constructor and destructor summaries, and allows us to name member fields with a underscore suffix instead of 'this.' prefix (to follow chrome C++ style).
