title: C# gpgpu in winrt
body: <p>Basically the question is how do I run gpgpu code in a Metro app. The library doesn't need to be dedicated to computing, for example, using XNA's hlsl (originally intended to render things) for general computing (XNA is not included in Metro, hence my problem). A default Metro library is preferred over a reference to a external one.</p>
  
  <p>I realize that one may call core DirectX functions in C++, however, I am asking if it is possible to use the gpu in C# in a metro app.</p>
