MicroServiceName =(from ms in db.Microservices where ms.ID == userInfo.MicroServiceiD select ms.AppsDesc).FirstOrDefault(),need to get comma separate value here

DevicePropertyName = (from prp in db.PropertyMasters where prp.PropertyId == userInfo.DevicePropertyId select prp.PropertyDesc).FirstOrDefault()

}).OrderBy(o => o.IMEINo).ToList();
