typescript - namespace problem not defined

this is my client class:

namespace Core {
    export class Client {}
}

and I create a new object like below:

let client = new Core.Client();

but I get this error:

/dist/index.js:10
    let client = new Core.Client()
                 ^

ReferenceError: Core is not defined
    at Namespace.<anonymous> (/dist/index.js:10:18)
    at Namespace.emit (events.js:314:20)
    at Namespace.emit (/node_modules/socket.io/lib/namespace.js:213:10)
    at /node_modules/socket.io/lib/namespace.js:181:14
    at processTicksAndRejections (internal/process/task_queues.js:79:11)

what is the problem?

You need to reference your namespace in your index.ts. So if Client is in a file called core.ts you need to do:

/// <reference path="core.ts" />
let client = new Core.Client();

And you need to export your namespace:

export namespace Core {
    export class Client {}
}

See the handbook for more information.
