NowSo I needed to create a Hololens 2 App and deploy it to an actual Hololens 2 that I had with me for development, AND I needed to save a copy of the compiled app that could be copied onto a Hololens 2 that my client had in another office. It was a very convoluted process so I thought I would document it now so I wouldn’t forget it for next time round.

 

Before you start make sure you have the following

Unity 2019.4.4f1 

MRTK 2.4.0 

Visual Studio 2019

 

The Best Tutorial on Set Up

I could go through and tell you how to create a Unity file that will run on the Hololens2, but really, just follow this one that Microsoft put out. It is the best.

https://docs.microsoft.com/en-us/windows/mixed-reality/develop/unity/tutorials/mr-learning-base-01

Just go through that page and you have set up your basic Unity MRTK file that compiles to the Hololens 2 through Visual Studio.

 

HOW TO CREATE A FILE TO SEND TO SOMEONE TO INSTALL

This is where is gets fiddly and you need to set up certificates and stuff. So…. let’s get started

 

In Unity, open your Player Settings File > Build Settings > Player Settings.

In the Player Settings Window Expand the Publishing Settings

Scroll down to  the Certificate section and click the Create… button

 

 

A pop up box will appear and ask you to fill in a Publisher (I usually put in either my client name or my Sole trader name), and a password. Do this and then click Create

 

 

Now go back to Visual Studio and in the Solution Explorer window expand your app and locate the Package.appxmanifest file. Click on it to open it.

 

 

Click on the Packaging heading and then click on the Choose Certificate button

 

 

Click on the Select from file… button

 

 

Navigate to  the Project Assets folder (make sure it’s not the Builds Asset folder!) and select the WSATestCertificate.pfx file

 

 

Now remember in Unity we gave the certificate a password, you’ll need to enter that now and press OK

 

Now click on View Full Certificate

 

 

And click on Install Certificate

 

Choose the Current User radio button and click Next

 

 

Choose the Place all certificates in the following store radio button and click Browse

 

 

Choose the Trusted Root Certification Authorities and click OK

 

 

Click Next

 

 

Click Finish

 

 

You’ll get a Security Warning. Click Yes

 

 

Then you’ll get a message that the Import Was Successful. Hit OK

 

 

And click OK

 

 

Now right click on your app in the Solution Explorer Your App > Publish > Create App Package

 

 

Select Distribution Method. Choose the sideloading radio button and click Next

 

 

Make sure the radio button Yes use the current certificate is selected and click Next

 

 

Hololens2 needs ARM64 so make sure that checkbox is selected also and hit Create

 

 

Navigate to the folder in Windows Explorer that you gave as your file path to save the packages, and you can send these to your tester to save onto their Hololens 2.

 

 

I have another blog post that shows you how to copy it onto your Hololens 2 here
