Draw Line Using Web Application In TypeScript

In this article, we draw a line using a web application in TypeScript.

First we download some files in the following attachment:

  1. Kinect.d.ts

  2. Kinectic.min.js

These file are added to the project then the following procedure is used.

Step 1

Open Visual Studio 2012 and click "File" -> "New" -> "Project...". A window is opened. In this window, click "HTML Application for TypeScript" under Visual C#.

Give the name of your application as "Draw_Line" and then click Ok.

Step 2

After this session the project has been created; a new window is opened on the right side. This window is called the Solution Explorer. The Solution Explorer contains the ts file, js file and css file and aspx page.
