Angular 2 - nswag converting classes from c# typeScript #2800

Hi,

I created a service with an whose has got a function with a class as input.

public async Task<ListResultDto<ArbeitszeitListDto>> GetArbeitszeitenAsync(ArbeitszeitenInputDto input)
        {
                  
        }

The input class "ArbeitszeitenInputDto" looks like

public class ArbeitszeitenInputDto
    {
       
        public int? MitarbeiterId { get; set; }

       
        public int? MaschineId { get; set; }

       
        public string Filter { get; set; }
       
        [Required]
        public DateTime StartDatum { get; set; }
       
        [Required]
        public DateTime EndDatum { get; set; }
    }

But only for this class, nswag doesn't gernerate a class. For all the other classes I created it worked fine.

=> Angular2 => service-proxies.ts generated code:

/**
     * @return Success
     */
    getArbeitszeitenAsync(mitarbeiterId: number, maschineId: number, filter: string, startDatum: moment.Moment, endDatum: moment.Moment): Observable<ListResultDtoOfArbeitszeitListDto> {
        let url_ = this.baseUrl + "/api/services/app/Arbeitszeit/GetArbeitszeitenAsync?";
        if (mitarbeiterId !== undefined)
        
            url_ += "MitarbeiterId=" + encodeURIComponent("" + mitarbeiterId) + "&"; 
        
        if (maschineId !== undefined)
        
            url_ += "MaschineId=" + encodeURIComponent("" + maschineId) + "&"; 
        
        if (filter !== undefined)
        
            url_ += "Filter=" + encodeURIComponent("" + filter) + "&"; 
        
        if (startDatum !== undefined)
        
            url_ += "StartDatum=" + encodeURIComponent("" + startDatum.toJSON()) + "&"; 
        
        if (endDatum !== undefined)
        
            url_ += "EndDatum=" + encodeURIComponent("" + endDatum.toJSON()) + "&";

        const content_ = "";
        
        return this.http.request(url_, {
            body: content_,
            method: "get",
            headers: new Headers({
                "Content-Type": "application/json; charset=UTF-8", 
				"Accept": "application/json; charset=UTF-8"
            })
        }).map((response) => {
            return this.processGetArbeitszeitenAsync(response);
        }).catch((response: any, caught: any) => {
            if (response instanceof Response) {
                try {
                    return Observable.of(this.processGetArbeitszeitenAsync(response));
                } catch (e) {
                    return <Observable<ListResultDtoOfArbeitszeitListDto>><any>Observable.throw(e);
                }
            } else
                return <Observable<ListResultDtoOfArbeitszeitListDto>><any>Observable.throw(response);
        });
    }

Is there somewhere a mistake or why didn't the nswag generate a class from it ?

Greatings,
