Idea to make the Date type useful in v1 as well & fix the Date serialization issue (https://github.com/microsoftgraph/msgraph-sdk-php/issues/704)..

Would it be worthwhile to make the setters for Date types continue to accept a DateTime but set the property to a Date via createFromDateTime and getters for Date types continue to return DateTime by creating a DateTime from Date's __toString()? e.g for RecurrenceRange

   public function setEndDate($val)
    {
        $this->_propDict["endDate"] = \Microsoft\Graph\Core\Models\Date::createFromDateTime($val);
         return $this;
    }
    
   public function getEndDate()
    {
        if (array_key_exists("endDate", $this->_propDict)) {
            if (is_a($this->_propDict["endDate"], "\Microsoft\Graph\Core\Models\Date") || is_null($this->_propDict["endDate"])) {
                return new \DateTime((string)$this->_propDict["endDate"]);
            } else {
                setEndDate($this->_propDict["endDate"]);
                return $this->_propDict["endDate"];
            }
        }
        return null;
    }

Unfortunately this might have undefined behaviour where it sometimes returns DateTime type for the getter sometimes Date depending on the type of the property on the propDict.

Okay. I'll need to think more. We can leave Date out of v1 for this PR
