Change Case(incident) statecode in crm 2016 online

I am aware of the early bound solution:

var incidentResolution = new IncidentResolution
                            {
                                Subject = caseproblemsolutionText,
                                IncidentId = new EntityReference(Incident.EntityLogicalName, incident.Attributes["incidentid"])
                            };
 
// Close the incident with the resolution.
var closeIncidentRequest = new CloseIncidentRequest
{
    IncidentResolution = incidentResolution,
    Status = new OptionSetValue((int) incident_statuscode.ProblemSolved)
};

service.Execute(closeIncidentRequest);

Is there any other way of changing statecode of incident using plugin without needing to generate IncidentResolution class using CrmSvcUtil.exe tool.
