I'm trying to support a legacy app I made a year ago and need to use jQuery AJAX calls to get data from the server. I have a JsonHelper class that I use to serialize DataTables and DataSets. This normally works fine in .NET 4.0, but .NET 2.0 there is no System.Web.Script.Serialization library and therefore no JavaScriptSerializer class.
I've tried to find another JSON serializer, but so far I can't get anything to work.
I tried using JSON.NET 2.0 http://json.codeplex.com/releases/view/13099 but it said it needed a higher framework. So I tried JSON.NET 1.3.1 http://json.codeplex.com/releases/view/6987 I could only figure out how to write JSON to a .txt file, and I'd like to just be able to pass the string back to the client.
I also just tried JsonFx.NET http://jsonfx.net/download/ serialization library (for 2.0). Still couldn't get anything to work.
I don't know if I'm missing some crucial element of these libraries or if there is an easy solution.
Thanks in advance
I used this question's first answer to solve my problem: DataTable to JSON
I downloaded the AJAX Extensions 1.0 Library and included "System.Web.Extensions.dll" with my project. http://www.microsoft.com/download/en/details.aspx?id=883
JavaScriptSerializer now works.
