UWP plugins xaml parsing error

I make UWP DLL with xaml
exports vs project and build it. but occupied “xaml parsing error”

‘UWPSample1.exe’ (CoreCLR: CoreCLR_UWP_Domain): Loaded ‘…\UWPSample1\bin\x64\Debug\AppX\System.Resources.ResourceManager.dll’. Module was built without symbols.
Exception : XAML parsing failed.

DLL file settings
/asserts/Plugins/my.dll
/asserts/Plugins/WSA/my.dll

Env : Unity3D 5.2.1p3 / VS 2015

Was there a my.pri file as well somewhere ? If yes, maybe it wasn’t properly copied?

Thanks @Tomas1856
pri file was same directory

upload asserts directory in my unity project.
please check settings. thanks.
