Question

I’m building a winForms app in NET3.5SP1 using VS2008Express. Am trying to deserialize an object using the System.Web.Script.Serialization library.

The error is: Type ‘jsonWinForm.Category’ is not supported for deserialization of an array.

Cheers!

It’s great you found your error. If you are looking for another tool for JSON serialization you might want to try JSON.Net.
