Does not work when "required" keyword is used in property declarations in class

[douglasg14b]

Example:

    public class ExchangeOverflowCompletedResponse
    {
        public required long OverflowId { get; set; }
        public required Resource Resource { get; set; }
        public required double Quantity { get; set; }
        public required double Fee { get; set; }
    }

Converts to:

export interface ExchangeOverflowCompletedResponse {
    resource: required;
}
