Introduction To HoloLens

In this article we will discuss how we can understand the HoloLens prerequisites, such as setting up the environment and so on. We can build holographic apps and run the apps in the HoloLens device. There is no separate SDK for HoloLens, we can build holographic apps using Visual Studio 2015 with the Windows 10 SDK.

Actually, I was eager to learn HoloLens when it was introduced by Microsoft, but unfortunately it is very costly --  $3000 for one device. Microsoft has now introduced the HoloLens Emulator for Visual Studio 2015. It is highly recommend to install the Unity game engine as an easy way to get started creating holographic apps.


Holographic is a mixed-reality platform development by Microsoft and it's built around the API of Windows 10. It uses various sensors, a high definition stereoscopic 3D optical head mounted display, and spatial sound to allow for augmented reality applications. It responds to you gaze, gestures and voice commands, and can interact with real world surfaces around us.


You have to download the following software and install them on your PC.

  1. Windows 10
  2. Visual Studio 2015
  3. Windows 10 SDK
  4. HoloLens Emulator
  5. Unity HoloLens Technical Preview

Visual Studio 2015 Community Edition

You can download and install the free community edition of Visual Studio 2015 from Microsoft Developer portals.

HoloLens Emulator

It enables you to run the apps on Windows Holographic in a virtual machine without a HoloLens device. This package also includes holographic DirectX project template for Visual Studio 2015. You can download and install the HoloLens Emulator here


Your system must support Hyer-V for the HoloLens emulator installation required in your PC.

Unity HoloLens Technical Preview Beta 20

The Unity engine is an easy way to get started building a holographic app. HoloLens support in Unity is available through a custom version of the Unity Editor and Run time which is now available to download for free on the Unity website. You can download and install the Unity HoloLens here

System Requirement

Required hardware is Hyper-V and RemoteFx for the Hololens emulator

Windows 10 Pro, Enterprise, or Education with 64 bit. 

  • 64 bit CPU
  • CPU with 4 cores

You can select the features you want to install into your system and click Install button


Installing features is in progress as in the below screen shot.


After successful installation of the HoloLens Emulator, click Close button.


How to develop, build and run the Holographic App

We are going to discuss how to develop, build and run the Holographic Hello World App and show the demo in HoloLens Emulator. We will see the step by step guidelines for the Holographic Hello World App creation here

Step 1

Open Visual Studio 2015. Go to file menu, point to new and then click new project. New Project window will open, you can select an installed template like “ Holographic” under the Windows on Visual C# Template, and then select a Holographic DirectX 11 App (Universal Windows) and type Project Name HoloHelloWorld. Choose the project location path and then click on the OK button.
