Recently i found this blog http://oscarbg.blogspot.com/2010/03/cuda-30-and-nexus-in-vs-2010-cuda-on.html
]on how to configure and enable CUDA 3.0 development on VS2010.
The Author has provided an attachment for folks who do not want to go in deep inside the customization. Compile the projects inside the zip file and launch it to configure and integrate CUDA 3.0 project and Custom Compile rules to the IDE seamlessly.
Nexus integration was also successful but crashes the IDE many times. Visit the blog for latest tool upgrades.
Finally My heartiest thanks to the Author for creating this amazing tool.
