Accelerated Computing CUDA CUDA Programming and Performance

I am trying to using cuda in windows store app.

But when I call cuda api(bott cuda runtime api and driver api) alway return error code.

The error code is 'No Cuda Device".

I’m using cuda well in C++ or C# desktop application(traditional windows application) in Windows 8.1.

Thanks in advance.
