windowDays property
WindowDays is the length of the trailing window every count covers, so a reader knows whether 40 signups is a month or a day.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
int? windowDays;
