Generate C# classes from JSON

JetBrains Rider lets you generate C# classes based on existing JSON. For example, from the following JSON object:

        {
            "Description": "Remove braces",
            "Scope": "editor",
            "IdeActions": [
                {
                    "Ide": "visual_assist",
                    "Id": "BracesRemove"
                },
                {
                    "Ide": "intellij",
                    "Id": "Unwrap"
                }
            ]
        }
    

JetBrains Rider will create classes that describe the structure of this object, which you can then use to read JSON files with the same object structure.

public class RootObject {
    public string Description { get; set; }
    public string Scope { get; set; }
    public IdeActions[] IdeActions { get; set; }
}

public class IdeActions {
    public string Ide { get; set; }
    public string Id { get; set; }
}
    

Copy a valid JSON to the clipboard — this can be the whole text of a JSON file or one or more objects in the JSON format. If you copy a part of JSON file, make sure that the copy is a valid JSON that starts and ends with {...} or [...] on the same level.
Place the caret in a C# file where class declarations are allowed.
Press Ctrl+Shift+A or choose Help | Find Action from the main menu. In the popup that opens, start typing Paste Special: JSON as Classes, select the corresponding item and press Enter.
