@Gunter is absolutely correct. The only thing I would like to add is actually how to deserialize json object keeping its date properties as dates and not strings (from the referenced post its not that easy to see this approach).

Here is my attempt:

export class Helper
{
    public static Deserialize(data: string): any
    {
        return JSON.parse(data, Helper.ReviveDateTime);
    }

    private static ReviveDateTime(key: any, value: any): any 
    {
        if (typeof value === 'string')
        {
            let a = /\/Date\((\d*)\)\//.exec(value);
            if (a)
            {
                return new Date(+a[1]);
            }
        }

        return value;
    }
}

You can see this approach for example here: JSON.parse Function in the dateReviver example.

Hope this helps.
