The reason you're seeing that error is because you are using Q1 2015. We did not introduce support for Windows 10 until Q2 2015.
Please update your UI for Windows Universal to the latest version, 2105.2.624 and the duplicate xbf file error will be resolved. You can download the latest version from here
If you cannot update, then you'll have to directly reference the DLLs instead of the Extension SDK as a workaround. However, this is not recommended
when using the Map because it is dependent on the processor architecture. You'll need to reference either the ARM version or the x86 version of the DLL depending on what your current target architecture is. Please read this page
in the documentation for instructions on the topic.
