Windows Store app with Unity 5

[from2001]

Hi,
I am developing a Windows store app with Unity 5 with Leapmotion, but I got stuck with some error.

I use the latest version of environment
Unity 5.0.2f1
Leap_Motion_SDK_Windows_2.2.5
LeapMotion_CoreAsset_2_2_4.unitypackage

When I try to build Windows store app, I get two errors and cannot proceed.
1, Plugins colliding with each other.
2, Plugin 'SystemWipeRecognizerDll.dll' is used from several locations:
Assets/Plugins/x86/SystemWipeRecognizerDll.dll would be copied to /SystemWipeRecognizerDll.dll

Even after I restart my computer, the error occurs. It happens only for Windows store app.

Does anyone know how to fix this problem?

In your Assets/plugins folder, look in the x_86 and x_86_64 folder for the SystemWipeRecognizerDLL.dll file. Select it in the Project view so that its properties are displayed in the Inspector. Uncheck "Any Platform" and instead check "Standalone." (To use it in the Editor, also select "Editor" for the x86_64 version.)

Of course, if you aren't using the SystemWipeRecognizer, you could delete it from the project. too.

Hi Joe,
I checked "Stand alone" on DLLs instead of "Any platform", them I tried to build.

Now I got 999+ errors of the following.
Reference Rewriter: Error: type System.Runtime.InteropServices.HandleRef doesn't exist in target framework. It is referenced from LeapCSharp.NET3.5.dll at System.Single Leap.Vector::get_Yaw().

it seems System.Runtime.InteropServices.HandleRef doesn't exit in .net framework for Windows Store.

By the way, did you successfully finished building in your environment?

No, I'm not (personally) set up to build Windows Store apps, so I'll have to check to make sure we support this. At one time we did not support WindowsStore apps, but I thought we had fixed the issue. I could be mistaken. It could also be that the SystemWipeRecognizer itself isn't set up for the Window's Store requirements, if that's the only ell you are having problems with.

[Joe_Ward]

We don't officially support Windows Store apps. (We removed one of the impediments to passing the certification requirements, but don't test this configuration.) That said, one developer reported getting his app to work (https://community.leapmotion.com/t/windows-8-1-development-on-visual-studio-2013/325). I'm not sure if his results are universally valid or if the same technique can be used with Unity.

Hi Joe,
Thank you for the reply. I read the article, but it seems that the the solution may not apply Unity issue. I couldn't find any pages which mention about Leapmotion Windows app with unity at all.

Whn you have time, it would be very appreciated if you try building Windows app with Unity 5 using Leapmotion Unity Core Assets.

I´ve built a comercially leap app for Windows Store in 2014 but it´s a xaml app, not a Unity game.

Also i had to load dll´s manually and make sure .net 3.5 and 4.0 not conflict each other.

I had the same issue on Unity 2017 and Leap 2.3.x with a new project:

Reference rewriter: Error: type System.Runtime.InteropServices.HandleRef doesn't exist in target framework. It is referenced from LeapCSharp.NET3.5.dll at Leap.Interface.
