Does .NET 4 come with any class that serializes/deserializes JSON data?
I know there are 3rd-party libraries, such as JSON.NET, but I am looking for something built right into .NET.
I found Data Contracts on MSDN, but it is for WCF, not for Winforms or WPF.

JSON is a format that encodes objects in a string. Serialization means to convert an object into that string, and deserialization is its inverse operation (convert string -> object).
A common way to deserialize JSON is to first create a class with properties and fields that represent one or more of the JSON properties. Then, to deserialize from a string or a file, call the JsonSerializer. Deserialize method.
Json library is included in the runtime for . NET Core 3.1 and later versions.
The JsonSerializer is a static class in the System. Text. Json namespace. It provides functionality for serializing objects to a JSON string and deserializing from a JSON string to objects. The JsonSerializer has the serialize() method with multiple overloads, which is a highly performant method for serialization in .
You can use the DataContractJsonSerializer class anywhere you want, it is just a .net class and is not limited to WCF. More info on how to use it here and here.

There's the JavaScriptSerializer class (although you will need to reference the System.Web.Extensions assembly the class works perfectly fine in WinForms/WPF applications). Also even if the DataContractJsonSerializer class was designed for WCF it works fine in client applications.
