The currently available ANT Windows .NET libraries are built for the Intel x86 platform and use services from other (driver) libs that are native x86 Windows libs, not .NET libs.
I strongly assume that your "... store apps ..." are apps for the Microsoft Windows tablet world - which is ARM based, not x86 based.
That would explain why the existing .NET libs can't be used, ...
... but not answer your question if and when the ARM platform will be supported. That is definitely a question for Dynsstream staff.
