 <\/p>\n

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.<\/p>\n

 <\/p>\n

Before you start make sure you have the following<\/h3>\n

Unity 2019.4.4f1 <\/p>\n

MRTK 2.4.0 <\/p>\n

Visual Studio 2019<\/p>\n

 <\/p>\n

The Best Tutorial on Set Up<\/h3>\n

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.<\/p>\n

https:\/\/docs.microsoft.com\/en-us\/windows\/mixed-reality\/develop\/unity\/tutorials\/mr-learning-base-01<\/a><\/p>\n

Just go through that page and you have set up your basic Unity MRTK file that compiles to the Hololens 2 through Visual Studio.<\/p>\n

 <\/p>\n

HOW TO CREATE A FILE TO SEND TO SOMEONE TO INSTALL<\/h3>\n

This is where is gets fiddly and you need to set up certificates and stuff. So…. let’s get started<\/p>\n

 <\/p>\n

In Unity, open your Player Settings File<\/strong> > Build Settings > Player Settings. <\/strong><\/p>\n

In the Player Settings Window Expand the Publishing Settings<\/strong><\/p>\n

Scroll down to  the Certificate<\/strong> section and click the Create… <\/strong>button<\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

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<\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n<\/div>\n<\/div>\n

 <\/p>\n

Now go back to Visual Studio and in the Solution Explorer window expand your app and locate the Package.appxmanifest<\/strong> file. Click on it to open it.<\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

Click on the Packag<\/strong>ing<\/strong> heading and then click on the Choose Certificate <\/b>button<\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

Click on the Select from file… <\/b>button<\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

Navigate to  the Project Assets folder (make sure it’s not the Builds Asset folder!) and select the WSATestCertificate.pfx<\/strong> file<\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

Now remember in Unity we gave the certificate a password, you’ll need to enter that now and press OK<\/strong><\/p>\n

\"\"<\/p>\n

 <\/p>\n

Now click on View Full Certificate<\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

And click on Install Certificate<\/strong><\/p>\n

\"\"<\/p>\n

 <\/p>\n

Choose the Current User<\/strong> radio button and click Next<\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

Choose the Place all certificates in the following store<\/strong> radio button and click Browse<\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

Choose the Trusted Root Certification Authorities<\/strong> and click OK<\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

Click Next<\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

Click Finish<\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

You’ll get a Security Warning. Click Yes<\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

Then you’ll get a message that the Import Was Successful. Hit OK<\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

And click OK<\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

Now right click on your app in the Solution Explorer Your App > Publish > Create App Package<\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

Select Distribution Method. Choose the sideloading <\/strong>radio button and click Next<\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

Make sure the radio button Yes use the current certificate<\/strong> is selected and click Next<\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

Hololens2 needs ARM64 so make sure that checkbox is selected also and hit Create<\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

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.<\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

I have another blog post that shows you how to copy it onto your Hololens 2 here<\/a><\/p>\n
