Why can't servicestack deserialize this JSON to C#?

I am trying to deserialize the following JSON representation to a strongly typed object. I am able to serialize it from c# -> json, but not vice versa.

C#

public class Package 
{
   public Guid Id {get;set;}
   public List<string> Email {get;set;}
   public List<Items> Items {get;set;}
}

public class Items
{
   public string Uri {get;set;}
   public int Width {get;set;}
   public int Height {get;set;}
}

JSON 

{
    "Id":"84fd8751-6107-41af-9473-65aae51e042a",
    "Email":[
    "[email protected]"
    ],
    "Items":"[
       {"Uri":"http://localhost/foo.jpg","Width":234,"Height":313},
       {"Uri":"http://localhost/bar.jpg","Width":234,"Height":174}]"
}

Code to deserialize

var instance = JsonSerializer.DeserializeFromString<Package>(jsonData);

The object instance is created, and there are 2 item objects in instance.Items but all of their properties are null.

TIA

That is not valid JSON. The quotation marks around the value for Items should not be there.

You have quotes around the Items value, thus parsing them as a string instead of an array/list. Remove them to win.

"Items":[
       {"Uri":"http://localhost/foo.jpg","Width":234,"Height":313},
       {"Uri":"http://localhost/bar.jpg","Width":234,"Height":174}]
