How do you use the JSON Schema 'default' attribute in Json.NET?

If I have a JSON Schema that specifies a default value for a property, like

{
    "type" : "object",
    "properties" : {
        "foo" : { "type" : "string" },
        "bar" : { "type" : "string", "default" : "some text" }
    }
}

...and a JSON string like

{
    "foo" : "lorem ipsum"
}

...how can I deserialize that JSON string so that bar is set to "some text" (the default value) instead of null?

Solution

  • I traced the references in the Json.NET source code, and the default attribute is apparently parsed, but not used for anything. So, the answer to my own question is: You can't use it in the current Json.NET version.
