Affine Texture Mapping in d3d11/hlsl

Question

I am wondering if you happen to know how to change the default perspective correct texturing to affine texturing in HLSL or d3d11. I have to do specifically this for an assignment I am working on and any help would be great. THANKS!

noperspective float2 texCoords;
