I just noticed that there is a CUDA project template in VS 2010 Pro, presumably installed there by the CUDA Toolkit. So far, this template is an improvement over trying to set up the Empty Project template to build .cu code, since the latter is very error prone.
However, I find that this project template only offers a Win32 configuration, whereas I need x64. Should the CUDA Toolkit installer have put an x64 configuration in there, too? If not, where can I get one?
