Crushing after deploying on Windows IoT

We have windows UWP application (C#) and Raspberry PI 3. We use WindowsVisionSkillsPreview libs (from NuGet). When we run our application in desktop mode (x86/64) - everything is ok!

But when we try to run the same application in Raspberry PI 3 (Windows IoT/ ARM) we have an exception. We tried to register Microsoft.AI.Skills.SkillInterfacePreview.dll by regsvr.exe

var descr = new ObjectDetectorDescriptor()
HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)
