I am having a problem trying to implement the JavaScriptSerializer to parse a JSON string received from a server.

I implemented the following code:

responseFromServer = readStream.ReadLine();

JavaScriptSerializer ser = new JavaScriptSerializer();

var dict = new JavaScriptSerializer().Deserialize<Dictionary<string, object>>(responseFromServer);

var status = dict[notificationType]; 

Debug.WriteLine(status);

I added using System.Web.Script.Serialization;

Visual C# 2010 Express is telling me the namespace name Script does not exist in the namespace System.Web. As a result the JavaScriptSerializer is not valid.

What am I missing to use this, or is there a better way to parse the JSON string?
