Problem when serializeObject

Feb 5, 2009 at 11:11 PM
I created a simple function to try to serialize a string value into json, but got error.  I used stable Json.Net version 3.0

protected void Page_Load(object sender, EventArgs e)
string product = "MC SC";
string output = JavascriptConvert.SerializeObject(product);
myTextBox.text = output;

The error I got was "Could not load file or assembly 'System.Core, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.

the StrackTrace is:

Does anyone get the similar error?

.NET 3.5 is required.

It works beautifully.
