'LeapInternal' could not be found - Unity 5.5.0f3

[Clodo]

• Unity 5.5.0f3 , Windows 10 64bit
• Create a new project
• Import only Leap_Motion_Core_Assets_4.3.4.unitypackage
• Create the mcs.rsp file with "-unsafe" to avoid unsafe errors.
• It throw:
  Assets/LeapMotion/Core/Scripts/Utils/LeapUnityExtensions.cs(12,7): error CS0246: The type or namespace name `LeapInternal' could not be found. Are you missing an assembly reference?
  and many other (related errors). Don't start.

Any advice? Thx.

Our assets require Unity 5.6 or above.

I'm having this issue with the latest version of Unity, 2017.4.0f1 (64 bit). The only thing I do after opening a new project and importing the Unity Core package is the following: set Experimental (.NET 4.6) scripting runtime, IL2CPP backend, and .NET 4.6 API compatibility, then build for UWP (default options with 'virtual reality supported' checked).

What's really strange is that both this test program and my actual program function fine in the Unity Editor with the Play button, but fail during build with the original poster's error (and about 222 others related to missing classes like 'Frame'). Any ideas?

Addendum: I cannot build any UWP app with just Leap Core. Even a brand new project - no changed settings except for a UWP build - will not build. I've also tried every combination of scripting settings with no luck.

There is no UWP support, as it would require the development of a separate UWP SDK.
