Can I create a TypeScript type and use that when AJAX returns JSON data?

Question

I have the following C# class:

public class JsonBackup
{
    public int Added { set; get; }
    public int DEVCount { set; get; }
    public int DS1Count { s

Simplest way to achieve that is to create interface for IJsonBackup and when you receive json just cast it to IJsonBackup

interface IViewEvent
{
}

interface IJsonBackup
{
    Added : number;
    DEVCount : number;
    DS1Count : number;
    Events : IViewEvent[];
    Errors : string[];
    Rejected : number;
    Success : bool;
    Updated : number;
}

In your class definition:

backupDone(data: IJsonBackup, ajaxElapsed: any)
{
}

$.ajax("/Backup/Data/Backup",
    {
        cache: false,
        dataType: 'json',
        type: 'POST'
    })
    .done(function (data: any) {
        console.log(data);
        backupDone(<IJsonBackup>data, ajaxElapsed);
    });
